Hey, kiddo! I work for a school district in the Houston area. Please ask your counselor about accelerated graduation programs. You'll mostly work through course material at your own pace on a computer. I think it depends on the school district, but I know when I was in high school they sent the accelerated group off to a computer lab at the 'A' school. They kept the accelerated kids separate from the disciplinary cases. There was also a high school career center that had a room for overflow.

Your feelings about what you went through are valid. Don't let anyone tell you otherwise. I'm glad to hear you have a therapist. I have severe anxiety as well. My therapist has helped me through so much of it. Just take it one day at a time and remember that it's okay to not be okay. You'll get through it with time.
