Im failing school, what do I do?

Hi I'm a 19 F am currently in my second year of university. Since my family is in a difficult financial situation, I have to work full time while studying. My parents are both at the age of retirement and they have no stable income. So I have been the secondary breadwinner of my family for the past 2 years. Last year I took a break from school to work full-time, but my parents kept insisting that I finish university and they absolutely forbid me from dropping out, they kept scolding me about "how I'm just lazying around at home while I should be studying like my friends" last year. The thing is I never stayed home doing nothing I was always working, if not I was out tutoring middle school students. It just felt really unfair that they were criticising me for doing my best for our family.

Eventually I gave in and decided to continue university. It was fine in the beginning but handling a full time schedule of both work and school was exhausting, also I work the night shift so often times I would come home around 3-4 am and had to go my 7:40 am lectures. Now the real issue is with my midterms. Due to my sleep deprivation I slept through my alarms and missed 3 of my midterm exams, on top of that all my classes are incredibly demanding that I have started to dread at the thought of going to school. I am failing in all my classes. At this point I really want to give up, I know I need the degree for my future, and that I need to do my best since everyone else finished uni without a problem. But the only thing my parents wanted from me was to get a good education so that I can live a life better than "theirs".

Since we're in debt, giving up on my job is not a choice, without my job it would be impossible to pay for my tuition. I'm wondering if I wasted all of my tuition just because I couldn't handle studying and working. If it continues this will compromise my "future".

I really need some advise on this matter. I just want to give up on everything
