When they leave you because anxiety

So yesterday I tried to call my boyfriend and he said he was busy. I understood but at the same time felt bad because he was starting to change. To begin with on our first date we had sex and that was what worried me about him probably changing later. Before he begged me to call him all the time and wouldn't stop texting, stay up with me, etc. not after sex. The power of the 🐱 right?. I was feeling bad myself for having sex but I mean, he still keeps texting and being nice just not as before. So I decided to tell him I had anxiety and depression for a few months now (I did it out of nowhere so maybe he freaked out) and he said he used to too and that he knew I had that because it seems like it. So he suddenly tells me "I have to go, good night Jessica". Not even a cute name. Just I have to go after telling him how I am. I cried at night and felt like shit. I'm already preparing myself for him to leave me. I might be over thinking and over reacting but why would you just go to bed after me telling you that like it's not important?.
