Is it normal to be like this after a breakup?
I recently got back together with my first love after a long separation due to circumstances, including the fact he cheated on me when we'd already been together for 3 years. When we were back together we were together for a bit but his work commitments got in the way, he was acting cold and detached and he expected me to work constantly. Eventually, he cheated on me, again, I found out and then he said he didn't want to try with me anymore and promptly left and kicked me out his apartment.
I'm now unable to stomach food and whenever I try to eat I just feel sick, most of the time food isn't even on my mind, I also flipped out in a grocery store with my friend because I felt so edgy and frustrated and it was all making me feel really ill. I'm a big guy and work out a lot so I need to keep eating to keep my health and not sacrifice my regime for this weird food related emotional stuff. I've not heard of this before and I'm wondering if acting like this is normal or whether I should talk to my GP, what do you guys think?
