take some time and breathe.
what does this mean?
Leave the dojo...even if you call the dojo your family, leave it...take some "you time".
Mediate, listen to someone like Eckhart Tolle, etc., who can help bring back some stability and perspective in the way your outlook on life is. - Its good to have an anchor and his philosophy is quite practical.
Sometimes we can 'over-think' things...if you know what I mean.
So you may find it helpful to put this distance between you and all at the dojo for now.
At a later point in time, as you mentioned, you may want to go to another dojo in your city...who knows...but when the time comes the answer will be there.
As one rabbi says, "breath and heal" - "relax and heal"- "theres nothing to think about"...
