I know this is weird but it's not begging for attention it's an existential dread about passing unnoticed. I love you all and I wouldn't want my passing to go unnoticed, like most Americans I don't have adequate access to healthcare and there's more than a few of you whose absence I would mourn. Don't worry I'm not thinking of self harm it's just a thing that I think about sometimes and I feel I'm probably not alone.
Panic Attacks will always trick you into thinking its a heart attack.
Look up CBT techniques online to help yourself get control of them. Controlling breathing is the most important part of getting it to pass quickly.
Good luck anyway and you will get them under control with time.
Thank you, this actually helped me today.
