Although not an anxiety disorder, I have an "Anxiety tendency". I've tried to combat it for the last few months. When I get anxious, I feel like my head is boiling. It's not social anxiety, I feel like I'm gonna die at those moments. 
I prepare for the uni exam that I will have the next year, so I go to a cramp school as well as my ordinary online classes.
Last few days, I found an increase in my anxiety, as well as increase in my work program and stress.
It's becoming too much for me.
I'm so tired.
