When I get tired I can’t think straight and I get panic attacks. What’s wronh with me?

go to doctor

This could be your body's reaction of not getting enough of sleep. But I suggest you go to the doctor, it could be worse.

There's a good chance you're under a lot of stress right now, but we know very little about you.

I've been getting very positve responses to panic answers like this one. I hope it helps.

You need more sleep.
