So I am currently at University, and got a grade I am not happy with. I immediately spiralled for over an hour I was crying and terrified I'd have to drop out and left completely unable to rationalise what was going on. 

I wondered if anyone experiences this, and if there's anything you guys do? I am fully able to rationalise once I've calmed down and even get constructive things from the situation but in the moments when the issue has just happened.. I feel out of control. 

I am diagnosed with BPD and am in a relatively good place considering how I used to be.
