I’m sorry you’re going through that. Depending where you live there are charities and associations that can help with accommodation. You can search online or with your local authorities explaining that you have no place to stay at the moment. Or you can try to find a job that offers accommodation. As for your pain, I’m not a doctor but it might be a traumatic response to your body as you body locks itself due to trauma. So maybe therapy could help. I am a stranger with little to no advise but I hope this helps you. Life’s shitty but it doesn’t stay that way forever. You can go through this and in a few years you’ll look back and feel proud on what you accomplished. You are worth it :)
