Struggling with Mental Health and Career Path

i'm afraid. i don't handle failures very well. i am getting better at being kinder to myself, but i can't shake off my anxiety this time. basically, so much of my future is at jeopardy because of my mental health crippling me. the past few years i've been working really hard to get a volatile uni degree (in a tough field i struggle with) and pursue a secure job right out of graduation. but, my depression has gotten so bad that my grades have dropped significantly (like a 3.8 gpa to less than a 2.0). thanks to this, my uni education and career path are really shaky. i'm having to apply for so many things and fill out so much paperwork—which i'm not sure will even be approved—just to get a chance to still pursue the same path i've been on for three years. i just feel like these institutions put struggling people under more stress simply by nature of them suffering mental illnesses. it's not doing good for my anxiety. it would mean so much money that my parents put into me had gone to waste. it would mean i no longer get to spend much time with my closest friends because they all are on this same path as me. it would mean having to face my parents and confessing how i've been doing, which terrifies me for a number of reasons. i can't sleep or focus in class nowadays because of all the anxiety. i get cold sweats, wake up from nightmares, can't eat (or forget to), and get anxiety attacks. i'm too stressed. it's gnawing at me from inside out. i don't know where to go from here.
