I'm sorry that you're in such a rough spot. It sounds as though getting out into your own place will help put you into a better state of mind, and that's important!

It's good that you've gotten help to work through suicidal ideation ~ have you also talked with them about your anger and resentment towards your mom? I think that doing so would be very helpful for you. Letting those emotions out ~ speaking about them openly gives them a lot less power in your mind. Please do consider continuing seeing a T to help you work through your struggles.

Best wishes to you!
