Highschool student suffering from severe depression

Patient: Hello, I am an 18 year old senior in high school. It is not 1:40 Am and I cannot sleep. I am serverly depressed and these thoughts won’t let me sleep. My doctor prerscribed me 20mg Prozac but that hasn’t helpes so I stopped taking it. 2 weeks ago my 2 best friends an my gf of a year an a half moved. I feel incredibly lonely and I feel like i spiral deeper and deeper every day. Is there anything that can make this game away any faster or make me feel any differently? At this point I almost don’t want to feel at all and I know that’s not right. Please help me.

Symptoms: Sadness, anxiety, thoughts of suicide,
