Hey there
I'm really sorry to hear that you're going through this horrible ordeal. Do you have other family or friends you can turn to? I think turning to them would be your best option. If not, going to a homeless shelter would be a lot more safer than where you are the moment. It seems like you could contract any illness living in those conditions. I know it's a pride thing too, but really could things get any worse? That's why I think it's better to seek help from the homeless shelter - even if it does mean being split up [you can get back in contact once things change]. The homeless shelter will provide you with food, a safe place to stay and could help you seek help with employment. I really do wish you and your family, not forgetting your girlfriend, the best of luck.
Feel free to PM me anytime
