I messed up, but how do I get over it?

Lauren
I broke up with my boyfriend almost 2 months ago. The break up was definitely out of no where, I broke up with him, because I thought my anxiety and depression was stressing him out. I know I made a huge mistake breaking up with him, because he's such an amazing guy, but what's done is done. I can't go back....but it's been two months and I still think about him all the time. How do I get over him?
