Suggest Treatment For Severe Depression

Hi Im Fatima, I think i have depression, i took online assessment on mental illness and it said i may have severe depression. I felt so lonely since the semester starts. I so stressed on my academic performances, Im always late in classes and shows poor efficiency in school works which iam not before. Im also so anxious about the future, I always think someone i love may die anytime. I always think of something might happen out of the blue taht makes me very paranoid of everything. Im loner in college, i lost my former best pals in high school and they now got their new circle of friends in college thats why iam left alone. I barely talked to them since then, Im so sad and feel sorry for myself for letting my friends go just that easy and like we ve gone no memorable things in the past. i missed them so much. I also experience sleepless nights, usually i sleep at 4am and wake up by 12nn. Sometimes i barely sleep, maybe just 2 hrs and then thats it. Also there are times when i sleep a lot, especially when theres no classes. I think these things might be symptoms of mental disorder. I know its not yet late to seek for help, I feel so hopeless right now to the point that i have suicidal thoughts. help huhu thanks
