broken up with

I fell hard for this guy, and today he broke up with me. We've only been dating a short while but honestly this has been the hardest break up I've ever encountered. He messaged me saying this- 
I then phoned him to talk to him and he told me it was my anxiety that was his main issue. I have severe anxiety and a lot of things are hard for me, especially trusting someone. I don't have many close girl friends and I honestly just need some advice, and help on how to stop myself crying. 
He said that nothing was my fault, but that he's been having doubts since we started dating but he still thought it was okay to have sex with me and I feel extremely used because it takes me ages to be able to trust someone enough to open myself up like that. 
I don't know what to do anymore and I can't stop crying. Please help 😭
