I've been talking to a good friend on here for a few hours, she's really nice and helps my mood a lot, but I went offline about three quarters of an hour ago and then ten minutes later I literally had the biggest panic attack! I almost puked! I don't know why

And now I'm all dizzy, and I can see like the curtains moving when I'm looking at them and I'm unsure if it's my imagination or not... And I'm also getting Palinopsia which is sort of like trailing vision. Oh and it's 4:40 AM here and I'm scared to go to sleep in case I don't wake up

Is this all just anxiety or do you think smething might be wrong?
