This is kind of an odd question, but since this is by far the largest forum community I've ever been a part of, I figured it couldn't hurt to ask here.
Honestly, I attribute it to working in the cadaver lab and taking that biology class - I think it made me feel morbid after the fact -, but - for the past few months, I've occasionally had what I can only describe as ...mini-panic attacks. It usually happens when I'm trying to go to sleep, and it's always the same thing - I'll feel like I'm about to stop breathing. Or if I don't think about breathing, I'll stop. I don't have sleep apnea, and there's nothing else the matter with me, it's just all in my head. And I found out this summer that it's also made me more afraid of water - or, more accurately of swimming in water deep enough that I can't touch bottom. I feel like, if any water even gets in my mouth, I won't be able to breath. I'm more worried I'll get myself drowned in six feet of water because I freak out.
So far, I've always been able to calm myself down in a few seconds just by reminding myself that my lungs have worked without my help for twenty years and they're not likely to stop. But any other suggestions about how to prevent this from happening, or does this happen to anyone else?
