I was a healthy 23 year old. I have had a pretty rollercoaster 3 yrs. I had a baby young, lost my mother to cancer, moved to FL. came back to NC, moved in a stressful house(knowing it would be) had issues with the father of my child(now resolved) and lost my brother. I started getting the attacks maybe a month after I lost my brother. I was put on Zoloft(50mg), it seemed to be working, but only being on it for about 2 weeks I started to have fluttering around my heart. I saw my doc and she took me off of it. I'm also on birth control. Now I have insane thoughts that something is going to happen or something bad is going on in my body. I have these weird headaches. Sometimes I get them and sometimes I don't. It feels like my head has this fullness most of the time. Or I'll get this quick zapping feeling on one side or both. I have an app coming up and I will be bringing this up. I haven't had any of these symptoms since being on/off the meds and my birth control.
