You can only be "locked up" (committed to a psychiatric facility against your will) if you are a danger to yourself or others. Despite your witty "is" statement ("sunny with a chance of homicide"), it doesn't see to me that any of the things you are considering talking about with your T are anywhere close to dangerous, either to you or to other people. In fact, it seems that you have gotten quite a bit better and there is no reason to believe you will hurt yourself or anybody else.

I don't think there is anything wrong with being alone in the way that you have talked about, and nothing to be ashamed about the things you enjoy or "obsess" about.

Good luck,
Anne
