Have you just recently taken on all this or have you been doing it for awhile? If it's not indicative of a manic uptick, and you're happy with it, it's probably ok. Is it only your mom who has expressed concern about it? I might be reading a little too much into word choice, but is it possible that she's using this concern for her own ends? (That she wants more of you for herself, and is expressing it as concern over your mental health?) Again, I might be reading too much into your word choice, but something about it just caught me. Has she expressed specific concerns? Does she tend to be overprotective?

I'll stop inundating you with questions now, lol.

Welcome to the forums, btw!
