Going through a hard time?

I met a guy who ended up destroying me. We ended up in a relationship which turned out to be a complete lie. He ended things with me through text while my mum was going to have surgery in a few days to remove cancer. I found out he was married the whole time. He lied to me about his name, job, everything. He pretended he wanted to be with me. He pretended to care about me. He was intimate with me. I can’t even describe the hurt he caused me. I was nothing but kind and loving to him but he betrayed me and it destroyed me. I ended up on antidepressants. All I did was love him and I get this in return. It’s just so hard. I just want to feel like me again and feel happy.
