<human>: Give me the gist of the text in a nutshell

Last year our relationship was a roller coaster, I was diagnosed with depression/anxiety, so I had to deal with that, I lost about 10kg last year because I kept getting sick and wasn't able to eat every time we had a fight, and he had to deal with me being crazy and worried ect. I was constantly afraid he would leave me for this other girl ect.Don't get me wrong, he was a great guy. I just don't think we both dealt with things very well.  Anyway, we split up for a bit, I got heaps better, and stronger I guess, and we got back together. And its been great. Ive had trouble with a lot of my close friends last year (including that girl) so we are pretty much not friends anymore. Neither were they friends with my bf. However that suddenly changed when he started talking to that girl again, obviously just as friends, but Im getting those horrible feelings again. He went out with all my old friends, I try so hard to be cool with it but I feel sick again. I love him to death, but I don't want to be crazy again this year. How do i stop it? How do i deal with it? I keep thinking he will get sick of me, all those kind of thoughts are coming back. And I don't really have anyone else to hang out with anymore (all my other friends are single males- great guys who know im taken but it obviously would bother the bf and I wanted to keep things going great this year) so I dont know what to do.
