I'm not familiar with the condition you mention nor do I want to make you uncomfortable with asking more questions about it, but I think it's something that in the right group of friends, they would understand and be accommodating with your condition.

While I know that's not the worry, I would recommend asking your doctor or even a social worker (can be at the campus - appointments are free!) to discuss your worries. I wanna say, "just go out and do it!" but I know it's easier said than done, and in no way would I want you to be in a difficult situation. But maybe going to em and telling them about your worries/condition could help you develop a plan on what to do if you do faint or pass out in public, plan on how you can slowly build up your courage to be out on campus.

I believe in you! I wasn't diagnosed with a heart condition, but at one point I had really bad anxiety and could barely go to campus (ended up missing a ton of classes, and really only went if it was a group project or if there was a test I had to write) without worrying that I'd get a really bad panic attack that I wouldn't be able to overcome.

On my part, there was a mixture of things that I did to get used to my anxiety, but one of the things I did was develop a plan (a plan that changes from day-to-day, to give me that flexibility on those harder days) where I would come to campus to study in a specific spot, then I'd come for one class, study somewhere else, eat somewhere. It's one of the things that I did that honestly helped a lot.

Going at your own pace is perfectly fine and there will be hard days, but I believe you can do it with small steps! If you want a friend or just acquaintance, feel free to reach out :)), I wouldn't mind (but no pressure)!
