I am a high school student (16M) and I think I have a severe anxiety issue. I have an upcoming board exam (in 3 months), my prep is going alright, but I can't stop worrying. Somehow I also frequently worry about college applications (is it too early for a 10th grader? idk), what might happen if I don't get into a good school, and end up crying. 

Quite often I get so much upset that I stay in the bed for hours brooding. I lose motivation to study, and at the same time, hate myself for wasting my time. I need advice.

Thank you for reading.
