Hey Manny. Based on reading your posts over the last year or two, I suspect you may have been dealing with depression for a while. Please talk to your doctor and see if he has any suggestions.
In addition to whatever your doctor might prescribe, this may be a good time to make some changes to your martial arts training that you've been agonizing over for a while.
If you're anything like me, regular martial arts training is part of how you maintain your mental health, maintain balance, and fend off depression. I know from your posts over the last few years that you are unhappy with the changes made by the head instructor at your school and you are no longer satisfied with the TKD training that is available to you. You've looked at the other arts available to you (Shotokan, Kenpo, Judo, and Aikido if I remember correctly?) but you haven't been able to bring yourself to decide to make the switch. I'm strongly suggesting that today, right now, you pick one of those other schools and go for it. If one art isn't calling to you more than the others, then just pick the one that's most convenient in terms of location and class times. If you end up not enjoying it, you can always try something else later. Right now you just want to get yourself back into the routine of going out at least a couple of times per week, learning something new, challenging yourself, getting some exercise, and making some new martial arts friends.
