Okay so basically let me start with this. I'm an anxious person and I've had panic attacks before and they appear once in a while but this time it's different and it's weird. It all started in Saturday at midnight. I was lying in my bed and suddenly that feeling of a panic attack was starting to kick in out of nowhere. The symptoms were similar to any other panic attack I had except that this one lasted for 2 hours. It was going away and coming back in literal intervals of minutes and it was weird. When it finally went away I just went to sleep. The next morning when I woke up I was fine for first 5-10 minutes then after I got up out of my bed it started again, the same feeling. And it was strong I was dizzy af, my heart was pounding and I felt weak. That same day I had to go to my grandma's for lunch. I already promised I'd come so I had to force myself to go to her. I was walking and the whole time it didn't stop. I was sitting there at her place and the anxiety and the same feeling of panic attack were lasting for hours. When I got home and when I laid down on my bed a bit it slowly went away but when I would get up it would start to kick in again. I went to bed normally that night and slept normally. And then again when I woke up today everything was fine I was literally lying in my bed for 2 hours and as soon as I got up to go to the toilet I had the same feeling kick in again. And now I'm lying on my bed again and thinking what the fuck is going on? I never had a panic attack lasting this long and I never felt something similar to this. I've thought of having a heart attack and I do all the time but everytime I had a panic attack before I always ended up being wrong and I've already been to emergency care twice for the same reason and it was panic attack every time. But this is something I've never experienced before can someone help me and tell me what should I do and is there a possibility that it really is heart related? Or is just a long panic/anxiety attack thats gonna last for days?
