Triggered and can't get out of this funk

I have been away from my exn for 21 months. I spent a year and a half in therapy working on myself so that this wouldn't happen to me again. This past June I decided that I was ready to seriously date. I was confident and happy and my life was in a good place. I met several men and found something wrong with all of them. I'm not sure if it was my gut feeling or if I really was scared of having a serious relationship. Regardless, I met a guy in July who seemed nice. He wasn't my type at all which I thought was a good thing. My type hasn't exactly worked out for me. After one date I just didn't feel that it would be a good fit. I should have listed to my gut. He plead his case as to why we were a good fit and to please give him the chance to take me out to get to know each other better before making a decision. I allowed that and now looking back realize I felt pressured in to that date. We did have a nice time and long story short I ended up dating him exclusively. We had a nice time for a while but then I noticed that he seemed to be controlling and treated me more like a possession. He ended up smothering me with too much time together. I was already losing the independence that I had worked so hard to build. I ended up breaking up with him after he called me delusional. Of course he claimed to be joking. it didn't matter. I wasn't going to let anybody "joke" with me that way again. The break up happened 2 weeks ago and it has been awful. He kept texting and calling me and I asked him to respect my space. Two nights after I ended things he drove 1 hour to my house and let himself in and popped the lock on my bedroom door at 1AM to talk to me. That scared the crap out of me. He refused to leave saying he needed to be close to me. It was a long night for me to say the least. We talked over the course of the next week because he was sorry and wanted me to understand why he did that. I got sucked in to the conversation and he manipulated me like a puppet. I was so conflicted on what I event felt because he told me how I felt. He called my best friend the other night with a blocked number and said that I really love him and want to be with him and am too scared to admit that to my friends. I now have him blocked on my phone, on email and on Facebook and hope to never hear from him again. The problem is he totally set me back. He isn't a narc but he is OCD and became obsessed with me. I am now fearful of men, I can't think or focus on anything. I am incredibly depressed. I have no energy. I feel like I did after breaking up with my N. I'm not even sure what advice I'm looking for. I just need to express how I'm feeling and this place helped me so much in the past it just made sense to come here. I'm frustrated that I did so much work to love myself and this ass sent me spinning again!
