I don't know if I can do it anymore

i dont know if i cant keep doing this anymore i am struggling so much i cant get any uni work done and even if i do it is shit and i am still going to fail despite my best efforts because my best is never enough and on top of that i cant even take care of myself or my basic everyday needs i cant even get myself to drink enough water each day let alone manage my hygiene stuff i keep wanting to cry all the time and i keep having breakdowns over the smallest things literally dropping something on the floor is enough to set me off. then it is like should i quit uni but then i have wasted years of my life and incurred a huge debt all for nothing. i am exhausted 24/7 i keep doing stupid things because i feel so bad all the time there is nothing anyone can do to help me with all of this and i cant fix it myself even though i am trying really hard too and i just i cant take it anymore sometimes i feel like my only option is just to give up and die but then what if i fail and end up in the hospital again ugh anyway idk what to do anymore i am completely lost.
