Tori - welcome to PC. I am so sorry you are going through so much right now. It sounds like you are taking on a lot of issues that don't really belong to you. Put those issues back on the people they belong to and it will help you not feel so overwhelmed. I know, it's easier said than done. There are only so many things you can control and right now you need to take care of YOU. Please don't hurt yourself - the relief it provides is temporary and when that feeling of relief is gone, the issues are still there.
Hang in there! and keep us posted
