Backstory: I suffer from anxiety and have just started taking Citalopram again (about a week ago) but other than mild nausea I've never had trouble with it. I've also been doing a strict low carb diet for a month and lost a lot of weight.
Woke up this morning, after one of the most stressful weeks of my life, and immediately felt sick. I've been having trouble sleeping all week because of worry, although this has started to improve. I've also been struggling to eat.
I'd fallen asleep on the sofa last night, so got up to go upstairs to the bathroom. I was feeling very lightheaded and dizzy. I had to hang on to the banister and basically thudded down on to the loo seat, resting my head against the tiles. My vision was blurry and I thought I was about to pass out. I was running with cold sweat and trembling all over.
Finally, after what seemed like a minute, I started to feel a bit easier, and managed to get to the landing where I lay very still for about twenty minutes. I felt fine at that point, but maybe still a touch dizzy. After that I made it to the bedroom without incident and slept for a couple of hours. I'm feeling much better now, and have had a lot of carbs and sugar today in case that was it.
My worry is my heart. Although I haven't had any symptoms in the past, my dad's family basically all died from cardiac arrest. I had no chest pain/tightening/shortness of breath, but this is doing my anxiety no good.
Can someone who has had panic attacks or low blood sugar attacks say if this sounds similar to what they experience?
