My FP ghosted me at the beginning of the year and I'm still suffering from it. I was hospitalized twice when it happened and have been experiencing severe post traumatic stress and DPDR.  

It was such a horrible shock. She went from saying she loves me and planning a future together to completely cutting me off without explanation. 

One of the worst things is not knowing why. I can certainly make guesses but nothing seems like it's the right explanation. We even talked about in the event of her wanting to leave she'd tell me directly because I've been abandoned and ghosted in the past. 

There was a codependent element as well, as I made her and her happiness my identity, so when she left my identity went with her and I've been feeling like an empty shell.

Any tips on how I can cope, and heal and move past this? I've seen a few therapists but they haven't really known how to help me.
