Panic attack?

I was in my high school's gymnasium practicing a dance routine for a basketball game, which is tonight. I never get nervous about performing, I actually love performing which is weird because I'm a really shy person, so I don't know what even caused the attack. I was doing the dance then my heart started beating really fast, I got lightheaded/dizzy, my arms and legs started to feel really heavy, I felt like I was floating, my eyes were being....weird, it felt like nothing around me was real, I was shaking and I got really hot. It was terrifying. When I got into my car after the practice I just started crying and I couldn't stop, I finally stopped after about an hour. All I could think the whole time was "I'm going to pass out" and "I have a disease that's causing this". I'm fine now, kind of, but I have convinced myself that I have MS or another horrible disorder/disease, it's all I can think about 24/7. I can't even sleep anymore, I wake up in panic think about all of the things wrong with me, I even have dreams about it. I have become obsessed with Googling diseases and all of the symptoms, I know that this is a horrible thing to do, but I can't help it.
Anyways, back to my original story....I am now afraid to perform tonight because I am afraid that I will pass out. Does it sound like I had a panic attack? I am so scared thinking that it could be something else. I should probably add that I have an anxiety disorder and I started taking Buspar (5mg) about 4 days ago.

I hope you were able to do your routine tonight!

Definitely sounds exactly like a panic attack. Sorry that happened, I know it's scary & frustrating.

Has the doctor run blood tests on you to check your vitamin levels, thyroid, iron etc?

Is this your first panic attack? I know you said you've been diagnosed with an anxiety disorder & put on Buspar but didn't know if you'd had an actual attack before?

You're not alone & this can be treated. When you get a chance, check out the anxiety resources pinned on the top of the forum. Educate yourself on it & try out the worksheets. They're free & very helpful.

Also, performance anxiety can happen outta nowhere. It's annoying but it happens. There are coping skills you can learn to help this (the resources have coping skills you can learn). Many movie stars actually have it or had it. I've googled "stars that have anxiety" & there are quite a few!

All of us here understand anxiety & panic & we all support eachother. We'll support you too! You're gonna be ok
