So, I've always been a kind of anxious person, but it never used to be anything major or any real problem. But, lately it's gotten bad enough that I can barely leave my house. I feel tense all the time and my hands shake like crazy. My psych teacher said that it sounds like a Generalized Anxiety Disorder. I didn't tell him how bad it's been getting. I'm so scared and alone right now. Sometimes when I get like this, I black out and I "wake up" with new SH marks

I don't know what to do, I'm so nervous right now that I'm going to do something stupid.
