I have had health anxiety for past 18 years and I have recently been like I am gonna faint. I have felt dizzy and stuff but this seems like I am really going to faint. I did faint two weeks ago. I woke up at 3:30 am and my tongue was swollen on the right side and I don’t know if it freaked me out so bad but I ended up passing out on the floor. I keep feeling like it’s gonna happen again.
