I am having bad PMS recently, the worst PMS I've ever had. Bad stomach cramping, nausea, and vertigo. What happened today, however, frightened me to death. I noticed that I suddenly got tired/fatigued right before I left the house to get something. Once I came back, I realized I hadn't eaten in all day and ate a really sugary honey bun, figuring the fatigue was from a drop in blood sugar. I went and put something down, and I forget what I was doing next but I got very lightheaded and almost fell down. This lasted two seconds before I went back to normal but still frightened me nonetheless. Than, derealization struck me and I didn't know if anything was real. It went away after a few seconds but I am in bed now. I've had chest pressure for a while but now I'm afraid it means something else. I've also had bad shortness of breath when I got tired, as in I felt like I wasn't getting enough air.
I'm 15 and had a clear EKG back in June, I've had my heart listened to in December and was told I was healthy. :'( I really need help. I've also had stomach pain right below my belly button and have been nauseous as well, and I'm still a bit tired even after eating sugary snacks. I'm trying to drink more water as well. This has never happened in PMS's past but my PMS for the past 7ish months have been just getting worse. HELP? I'm really scared of SCA or something.
