<human>: Can you succinctly summarize the text in 1-3 sentences?

It's been 2 and a half to 3 years since me and my ex girlfriend split up and I can't seem to move on or get over her. She still haunts my dreams turning them into nightmares. I don't know how to let go or move on. She was the only thing that made things made me feel safe and secure and I'm just completely lost with out her. I don't know how I'm going to start over with someone else I don't know how I'm supposed to just forget her. 

I had a fucked up childhood and I have dysfunctional parents who take their shit out on me and I've lost the only good thing I had. I work out like crazy and I'm in the best shape of my life on the outside but on the inside I still just feel lost, empty, hurt, alone and I just don't know what to do. I've lost all my confidence, self esteem and any self worth I had. I don't know if I can even start over in a new relationship, I'll just be terrified of that person leaving like she did and I know it's completely unreasonable to expect anyone to be there for me forever.

I don't know what to do anymore people of reddit. I thought it would be getting easier now after this long but it still hurts so badly so often. I feel like a weak little bitch and that a man should be able to just move onto someone else and be okay. But i'm not. I feel like it's getting harder to cope shit instead of easier. I don't know what to do anymore. Please, any advice would be appreciated. Thanks.
