I am dying in school

It's barely been half and hour since school started. I'm in school physically and seeing all these people looking so happy makes me feel way worse. This is so painful. O don't know if I have anxiety but looking at all these people and being around them makes me extremely anxious and scared and I don't know why I can't even stop fidgeting. I don't know how I'm gonna continue this. I am really dying now. A while ago they did morning reflection cos I'm in a Catholic school and they were shoving faith and stuff into my face and while I was so painfully hopeless listening to people talk about why you should have faith made me feel even worse because there's no place in me for faith and hope. This is scary and painful. Nobody can help me either. Too bad I failed my attempt to die a few days ago. Hopefully no one notices the scars on my wrists. Pls help someone, even though I know nobody can.
