You are right, and I am sorry. I am just frustrated right now because I have put so much blood, sweat and broken/sprained body parts into this and it seems like it is coming to a pointless end to me.
But for me to damn the entire martial arts world and all of its styles, is immature and wrong, at best, and I apologize for that!

Hopefully this thread has been helpful and if anything gave you something to think about, other than just feeling better about quitting the school. However I don't see the need for it to come to a pointless end for you. I think you need to change your perspective on how you're training.
At first you posted that you liked the school (the MMA), you were getting a good workout, good instruction, liked the people etc. etc. and you later posted that the Tang Soo Do school didn't meet your needs because it was sport oriented, you were the oldest one there with a bunch of kids. Later you posted that the BJJ school was nice but you had learned some things about it that dissatisfied you; like you felt that BJJ wasn't effective on the street, you liked the Muay Thai but it wasn't taught much, the Boxing was OK, but you were learning three sports instead of the self defense aspect of the arts which is what you were really after. Now it all comes crashing down that it is all pointless because it isn't real self defense.
1) Nothing is real self defense in that everything you do in the dojo is controlled/cooperative simulations. In BJJ you do ground work and you work towards submissions, however the drill can be changed to where one person goes for the submissions and the other could go for more self defense related techniques like grabbing for the throat sticking his fingers into the eyes etc. etc. Do the same drill and have one person have a folding training knife in their pocket that they need to get it out open and stab where the other persons job is to watch that and prevent it from being deployed. On wait you don't wear pants in BJJ class, but for a SD class why not. In Tang Soo Do your one steps could teach fancy kicks and or sparring techniques or they could include take downs and stomps, arm bars, locks, whatever. You could expand the concept of the one steps to include defenses against kicks and tie in your Muay Thai low line cut kick to the supporting leg, or the foot sweep from BJJ or any art for that matter. Ultimately I believe it is how the simulations are used or set up are whats really important and tells you what focus of the school is.
2) Motion is motion so any move (I'm referring to a general concept here) can be used in multiple ways. The lunge punch that you are attacked with in one steps represents a lead punch or a really committed jab, the reverse punch represents a punch coming from the rear like a cross punch in boxing. The arm bar that you learn from BJJ can actually be a arm break of a shock to the arm to make it un-useable in the street, just like the down block can be an arm bar, the knees in your MT can be used for self defense, just like the elbows etc. etc. The long stance in TSD can help you close the distance when faced with an armed attacker, or it can be used as you step backwards to off balance and throw a person to the ground, or as you step back it can help you gain distance for a kick.
3) Its the journey of getting there that counts, the more you learn the more you can see what is out there and what is different. If your focus is on self defense then you need to look at drills and say how can I apply it differently to a self defense related mode. Then practice it that way as well. Looking at your TSD forms from a different perspective such as how the moves relate to Self Defense instead of sparring will help you to see beyond the meaningless form into something that has value. I beieve that TSD practices the Japanese katas (perhaps with Korean names), but I think they stayed with the older forms. If so than look up Bunkai on you tube and you will see a lot of useful stuff. Try Iain Abernethey for self defense related bunkai that should apply to your forms. Likewise Dan Anderson has a book on Modern Arnis (it is the empty hand book) that because MA had a Shotokan influence in it for it's Anyos (forms) has a very good section in that book that deals with motion application of traditional blocks (it opened my eyes).
Next I would look for a school to train in. I know finances are tight, but I would look and train somewhere in the near future. In all of these examples I gave you you need a partner to work with. I know the schools might not teach this way but you could ask and explore some different outcomes of the drills. For instance you could talk with the instructor and in one step sparring ask if you can do take downs (go easy on your partner), ask if you can do more self defense related stuff. You mentioned about the TSD place as having to many kids, so what about the other dojos? Are they all filled up with kids? Even though it might be a TKD, or a karate school that instructor might be dieing to have an adult be interested in the applications or at least exploring the idea with someone. You never know.
There are schools like this out there, my school is like this and I teach at a Rec. Center. I teach my intermediate/advanced belts drills that I learned in Muay Thai seminars almost 20 years ago (elbow drills, knee drills), likewise I teach them take downs that I learned in JKDC Kali from Guro Inosanto and Modern Arnis from GM Remy and SM Dan Anderson, arm bars I learned in Aikijujitsu, applications from katas I learned from Tony Annesi, even applications from katas I watched on DVDs of Iain Abernethy. The thing is I teach what is commonly called American Karate (TKD) a bastardized version of ITF TKD. My focus, my ultimate goal is to focus on the SD related aspect instead of the sport and I don't have any adults in my TKD program. My students get to do knife and stick defense (advanced intermediates and advanced belts in their teens), mind you defense tactics only, I'm not teaching teenagers to stick and knife fight; still the focus is one building SD related skills. They learn the ITF forms but with more combative or SD related bunkai in mind, release from grabs, take downs, hair grabs and low line kicks etc. etc.
I mention this because if someone like you came to my class on a night we're doing sparring, you'll see all of the kids padded up and getting after each other and you might think this is a sport school, likewise on a night we are working on kata then you might say we do nothing but dance. Talk with the instructors see what they think, what their goals are or focus is for their school. You might be surprised and find one that fits what you want and is in your budget. Right now I charge less than your old school for 3-4 workouts per week, in fact at the first of the year I'm going up in price to $80.00 a month. I'm way under priced.
