I dated the same guy from the summer before 11th grade through three years of college.
We mutually broke up, but I became devastated. I barely functioned for 4 months. The first week I had dry heaves every morning, couldn’t eat, cried constantly. I would shake from nothing. Just sit there and shake like it was freezing, but it wasn’t cold. I lost 10 pounds in one week. A few weeks into it I was prescribed Xanax, thank God, and could eat a little more. I should have dropped out of the term, but I didn’t. Ruined my GPA, and screwed up some other school related things.
Worst situation I have ever been through regarding how my brain and body reacted, but not the worst situation I have ever been through. If that makes sense. In the end, he was a cheater, and a liar. I would have most likely been unhappy, or eventually divorced, if we had married.
