This right here stands out to me. It's not fair to heap all of that onto you upfront and expect you to sit with it or even help with it. Your job is not to fix this girl, and it sounds like she wants someone to fix her and make her life okay. The reality is that no one can help her heal the pain she is dealing with except her. At the very least I would encourage her to seek counseling from a professional, because she needs help that is impossible for you to provide without dragging yourself down in the process. If she refuses to get help, or makes excuses, or continues to lament how hard her life is and how much she hurts without taking any action to better her circumstances, then this cannot be a healthy relationship.
