Yes dear Lynn you sound depressed and I'm so sorry.

Depression is a horrible condition, and I wouldn't wish it on anyone. I've had it since I was a small child and I'm now 63 yrs old.
I think what would help you right now would be to talk with the school counselor. That's what they're there for. Yes, they help with study courses, but they also help with personal problems too. So talk with the counselor/advisor. I'm sure he/she will be of great help to you and will keep things confidential.
If things get too serious, you may have to talk with your parents about having them schedule time for you with a therapist. Sometimes it's necessary to get professional help. I've been thru therapy and it helped alot, but since I have clinical depression, I'll be on meds the rest of my life.
I wish you the very best Lynn. I hope you'll let us know how things turn out because we DO CARE.

God bless and take care. Hugs, Lee
