Nearly Homeless Autistic and Terrified

I don't know where to get some help, I'm 30/f diagnosed with autism a few years ago. I'm struggling with how to cope and my relationship has broken down, I'm having to move out by the weekend and have nowhere to go, no support from family just being told to get on with it and to be realistic. I'm feeling hopeless and extremely depressed. No idea how to navigate the world alone, feel like i cant support myself emotionally let alone anything else. Any advice would be really helpful thank you I'm desperate.
