why can't you see yourself training ever again? if you want to do it, then you should do it. i need some information before i can answer your question well. how long had you studied? what rank (if any) did you achieve? i have been practicing for quite some time now, teaching as well (if you didnt get that from the name lol) i feel as though my art is like breathing, if i do not practice i will stop being..... everyone goes through some down time of sorts. a dojo closed, you have to move, etc. but you shouldnt let it get you down.
