Re: aikido crisis. :(
That happened to me before. Like others have posted Aikido is a journey and sometimes it uncovers things. I was in the dojo 4 to 5 nights a week and loving it, but at one point I realized I had started college and never finished and suddenly my enthusiasm for Aikido was gone. I left the dojo and will finish college next June. I'm also starting Aikido again in 2 weeks and I'm now posting on this sight while I'm supposed to be writing my master's thesis! My enthusiasm is back!
Basically take a break - if you truly enjoy it you'll come back
