Why not start a side project? Don't know what to do? I'm sure there is something you use that you could make just as good or better start there.

You don't need a gym, maybe just go for a run near your house to start, less excuses to not do it.

Lastly, have you though of buying a journal? The actual act of writing your thoughts down (vs typing) is therapeutic and may help you to work through some of your emotions
