Terrified I will go blind

I looked at the eclipse for about 10 minutes of total minutes, across 45-60 minutes that I was outside; I was wearing sunglasses, and didn't realise they do nothing to help.

I have no blurriness or shapes, maybe a slight burning and I keep itching it because I got hair in by accident.

My friend say I will likely go blind, and I think in 6 hours, when I eventually wake up, I will start losing my vision.

I am a stupid idiot.

What should I do?
