I'm really sorry you're feeling that way

. I know we've spoken a bit about it before. I understand in some way how difficult it is when you're not where you thought you'd be in life and it seems impossible to get there. Are there any things constructive / hobby wise you can do at home? I don't have an illness but I can relate to how you feel in some way, especially with not being where I want to be in life and feeling like I will never achieve what I had dreamed of growing up. I feel like sometimes when I'm not concentrating on anything I can let my mind wander and get into a spiral of ruminating on every way my life is not fulfilling, which ends up making me feel worse.
I don't know if that is how you feel, but if it is, one thing that helps me is to set a goal - any goal - with something I enjoy. Even if I start small I can eventually channel my thoughts into it rather than more unhappy thoughts. Like at the moment I'm trying to get better at photography and read more. So I might not have my own home or family, but I've just spent my time enjoying a few good books which I wouldn't have done otherwise.
