You have been training for 6 years eh? well you can train on your own for a while i'm sure but you should really try to get back in although it sounds like you will if you can. Good look with that. I'd say get some training aids, kick bags, Makawara Boards and stuff to keep your training up you never know when you get back into TKD your class mates may be pleasently surprised that you are better than when you left.
