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

I'm a 25 yr guy who is at the point of looking at start his family. I had gone through a rough breakup of a 3 year relationship and 3 months later of happy single life and working on me a bit I met someone. She was amazing to me, I got to know her little girl which quickly took a liking to me. We looked at places together after some time and she was happy and excited. The morning we were approved I was so excited to tell her. She told me she needed a break. I said I respected her decision and went about my day. After dinnertime I got another message from her saying she had to work on herself for a bit and it wasn't fair to be with me while she did that.

She was gone, no break, just gone and there was nothing I could do to stop it or change anything. She was my best friend, we were so compatible, we loved being with each other. I am unable to process that she is gone. It happened so fast. I haven't eaten, really slept, and I haven't left my bed for almost an entire 24 hours. I went through two 3 year relationships ending but nothing has ever hit me like this because she was perfect for me.

I spent a lot of my life in crippling depression and don't want to fall back into that. I just can't stand how alone I feel right now, I feel like I'm exhausted and at the end of my ropes. I lost my best friend, I lost someone that was so amazingly kind and caring to me, I lost the look I had at being a role model and someone important to a child. I don't know how to bounce back from this and I don't know how to handle it. 

I have obviously because of my past thought about giving up, throwing in the towel, just sick and tired of the one thing after the other. However I know if I ever did anything she would feel worse and I can't do that to her. So I'm suffering silently here in my bed watching shitty YouTube videos crying in increments and throwing up at other times. 

I have no one to talk to about it now that she's gone. I told her everything.
<bot>: Relationship went from happy to gone in 7 hours and I'm completely falling apart with the chance of depression and crippling loneliness coming back. I need help and don't even know what to think or how to proceed.
