How do i become More Social and Gain friends If I have Chest problems when i Do?

Hi.

male in my early 30s. I’ve been shy all my life. But I’ve never just hidden to avoid stuff. Even though it takes alot of courage to do something, i do it. For example, talking to someone i want to talk to.

Anyways, with the shyness also comes anxiety. And as you all know anxiety can cause health problems. The thing is, when i have anxiety i try to relax but it doesn’t work. I get a big surge of butterflies in my stomach and chest just before talking to a stranger or something.

And it’s not just that, .. Yesterday, i tried talking to a girl In town( stranger). i mustereed the courage and i did it.( it failed by the way, she was shy herself and not interested in talking to strangers) But i felt a burning sensation in my chest right before doing it. and then a bit later i started getting Chest/Heart pain.

Then i was walking home and it hurt bad so i had to stop and sit on a rock in the street to see if it go away. Well, it did alittle but It’s 1 day after and I’m having pain in the middle of my chest.

It’s like just from that surge of anxiety yesterady, something in my body broke. I wouldn’t be surprised because I have a skinny little weak body ( Doctors have told me i may have Marfans syndrome) and maybe i have weak valves.

So, is it even worth it to try to change and be more social, when doing so is dangerous for my health?
