Why am I still so miserable?

If you read my previous questions, you’ll get my situation. Well, I’ve been very upset with a guy that I still…unfortunately love. I broke up with him cause I was done with suffering. Well, its many months later and im still not over this @#$%^&!!!

He’s dating someone new,that killed me. He gave her,her first kiss, that killed me. It led to all this drama cause they were bad mouthing me and my feelings being shot down. I heard that the a**hole things he’s done to me, he’s doing to her, and I heard that she told him a secret, and he ended up telling everyone he knew and she was thinking about breaking up with him, and that thought comforted me. But she forgave him like the stupid @#$%%^&%$!!! she is, and he bought her an expensive bracelet that says:

Sisters: For all her true best friends to stay together

Friends: Symbolizing when he and she were first friends

Forever: You get it

When I heard about it, I didnt want to see it and I didnt want to hear about it no longer. I’ve had a history of traumatic migraines, and I felt very drained out and my friends kept commenting on my upset expression. I was so miserable and weak-looking, I had to be sent to the nurse’s office. I began sobbing of my severe headache and I had an anxiety attack. They sent me home and I blamed it on the Prozac side effects and other medications, so I was downplaying it. I stayed home today, sobbing and swelling of my eventful schoolyear. I couldent stop hyperventilating, and im desperate to get over this @#$%^&*&%$#@!!! I’ve been miserable for 3 !@#$% YEARS!!! It feels like there’s no way out. Someone,anyone, please help me. -Crystal
