[quote ... I do worry about taking my medications with me (and also not having someone around who I trust who can say, "Hey, be careful!" Depression is awful, but the euphoria of mania can lead to really bad decisions.
Many others here can and have given you some good photo-food for thought. I'd like to add a bit of encouragement on the health issue:
Keeping in mind that reasonable emotional balance and the best physical health we can maintain is fundamental to all else we do, try to make that a priority that a moment's mania can't shake. Re. depression, absolutely maintain the meds, and consider the effects of living in an apartment with "no windows that admit light".
I imagine that you are familiar with the effects of S.A.D., but if not, read up a bit. The effects of a relatively sunlight-free environment can be very severe on some people, ...responses vary. In any case, more light on the subject(you) will add weight to the anti-depression side of the scale. [ SAD = Seasonal Affective Disorder. ]
If your intent is to actually become an income producing photographer, rather than a fulfilled amateur, consider carefully the many posts re. this idea on numerous photo forums. Reality can be much more demanding than dreams, ...especially if the dreams are fueled by both periodic mania and G.A.S. (Gear Acquisition Syndrome
I'm convinced that if an authoritative voice spoke from the clouds, decreeing that there would be no new gear available, most of us could nevertheless have some very rewarding experiences using what we already have.
Try for patience, and give yourself plenty of time for thought.
Congratulations on having such a supportive wife, and best wishes, whatever your decisions,
