I want to escape depression

I am just 20 years old. 4th year nursing student. Its been months since I had depression. I lose weight, i got so many hairloss, I don’t have the appetite to ear, my period won’t come, i get so many pimples, i have insomia, I’m so dehydrated, I can’t focus at school and fail on my exams and many more. I’m already a graduating student but I don’t know if i will be able to pass any of my courses today. I feel so sad, so alone and so empty. I’ve been having suicidal thoughts. Fighting against my mind whether i want to live or i want to die. But I really want to die. I want to end my depression. I am not happy with my life. I lost all interest in everything. I feel like this life is kot worth living anymore. People always leave me, they don’t care at all. But I want to be happy, I want to breathe. I want to feel alive again. I want to live instead of just surviving. I’m still very young, I want to escape this hell of depression. I want to see myself in a different place with different people and start a new and better life. I want to be free. I want to live and be happy again. So please help me.
