How To Get Over A Breakup?

I was in a relationship for a long time. My ex and I were together for 4yrs, but have been in each others lives for a little over 14yrs. At the end of 2020 my ex moved to Atlanta, but we chose to stay together. During our long distance I was the main one in his life, helping him in anyway I could (a lot financially).

November 2020, I had a really bad seizure, and had to leave school on medical leave (I have epilepsy). That seizure changed my life in a really bad way. It caused me to have severe anxiety, have panic attacks & everything, but I still was being a good gf & continued to be there for him.

This past January I went to visit him, and we had a good time, however I asked how could our relationship get better, he told me if I moved out there. I told him I would think about it because I was back in school. At the end of Feb. I left that college again because I had serious tuition issues that they refused to fix.

To make a long story short. When I left school, I was still there for him & in June he came home & broke up with me, without any explanation, and in a very disrespectful way. I was shocked, upset, and couldn’t believe it, but thankfully I didn’t allow him to see that reaction, I stood up for myself. However, since this happened, I haven’t been myself. I’m always crying, angry, feeling scared & I still can’t believe he hurt me so bad, I also feel like I’m going crazy.

I’m trying to get over it, but it’s been very difficult. I feel like he’s gone on with his life without even caring about me, like he threw me in the garbage. So, what can I do to help myself? Thanks in advance for the advice.
