In short, yes.
I can relate to a lot of what you have said. Overall, it has made me temper my personality as a whole. Like I try not to be too outgoing, because then that is what people expect from me and I can't be it when down. Mostly, I just avoid people as a whole when I am depressed. I can get away with this because I don't work (for the most part). I totally relate to the neighbor thing though. I am always, like hiding my face so xyz doesn't see me and then I have to make conversation.
The aspects of this that are most disconcerting to me is the fact that my personality is soooo different that I feel like I am not the same person. I feel like, what have I gotten myself into? why did I do this to myself? It is hard to live with the choices I have made kind of thing. Yeah, it sucks. But I just try to find the things that bother me most (like my big mouth and oversharing) and try really hard to control those things. Or really think twice before signing myself up for anything long term.
