Lost and lonely

I lost the love of my life. My soul is devastated. He and I are both struggling with mental health from past trumas. It's hard not having him in my life. We text every day and night but that's it. He said he doesn't love me. I know I have to find myself but I don't know how. I live with multiple scoliosis and the stress isn't good for me. We my ex and i watched my daughter try and commit suicide five time, being tied down to the gurney when she would try and escape from the ambos. Taking having her stomach pumped and being placed in a psychiatrist ward for 5months. She is in a better place now mentally which meds have helped. Her autism gets ahold of her.

It all caught up with my ex few years down the track. I can't help him he is in a dark spot and dislikes himself, he can't even talk to his parents. He has a counselor he talks to now. I have sane and a mental health nurse to talk to. I'm just so lost lonely and hurt. How does one find themselves happiness
