I can’t do this anymore

I feel like I‘m drowning under all of my emotions lately and I really can’t handle it anymore. I keep feeling like I‘m not good enough for anything. Last week I cried so much that my eyes had gotten swollen and I didn’t want to go to school. Now I just feel numb but sometimes this sudden rage against myself comes back up. I’m afraid that I won’t make it..... School is making everything worse as well.... please help....please
