Help me....please

I'm sort of in a panic right now. My bf recently left, I have no one to talk to, I'm alone and depressed and stressed. A year ago, I dropped forty pounds in one month due to stress and a neurological issue my doctors can't figure out. I'm having strong feelings of wanting to go back to that weight - even if it was unhealthy. That way one thing in my life I could feel good about. Advice? Also, how do I make friends? I'm not pretty, i have none😔

This was me
