The last two weeks have been a mental roller-coaster. Being screamed at by various people and being hounded by people for things that I did not even sign up for. I signed for an event 3 weeks ago, and now I am in no mental state to attend this. 

I am 16 and have been working hard in school and in other extra fields. about 3 weeks ago, I had signed up for an event and now, only a week before it I am about to have a mental breakdown. My head is hurting, my arms and legs are hurting and I feel a certain coldness inside me. What should I do about this.
