Re: aikido crisis. :(
There are two possible paths:
To take a break, without undue worrying about what the future will hold vis a vis aikido, just getting on with life and seeing if/when you start to miss it. If you don't, well, there is your answer.
To treat it like a temporary plateau and continue to show up and train, like putting one foot in front of another when one is depressed, just so that the normal life goes on and is still there when you actively want to resume it.
I honestly can't counsel you which path is best for you now. Best of luck and please let us know.
