No, you’re not needlessly exaggerating. You are hurting. Although it isn’t unusual for teens to go through periods of feeling low, you say this has been going on all your life. For that reason, I think you need to see a therapist for a while. I’m guessing the doctor who diagnosed you was a psychiatrist, not a counselor. Psychiatrists can prescribe medications but often don’t have the time to offer supportive therapy. When someone feels like you do, the treatment of choice is a combination of the two (medicine and counseling).
You haven’t totally given up on yourself. You managed to write to us here at Psych Central. Please build on that inner strength and make an appointment to see a therapist. Take your letter with you as a way to get the therapist up to speed. Due to your diagnoses, I do suggest you see if there is a DBT (dialectical behavior therapist) in your area.
While you wait to see a therapist, you can call the counselors at the Boys and Girls Town hotline, 800-448-3000, any time. They are available to talk to kids like you 24/7. It’s free and confidential.
I wish you well.
