Good evening, I'm currently am an undergraduate student in University of Arizona. Currently I'm in my 4th year and I have just few more classes to take before I can graduate but I have serious amount of my doubt about the possibility of graduating as my GPA is just barely above the requirement and I am having trouble even following the course material despite the hours of study I sink into these materials. Right now I'm at a loss on what to do, I know that I have zero hope on getting into graduate school nor any possibility of working in any science-related field with this academic state and I feel the main reason behind is my inability to grasp higher level abstract mathematics. The amount of hours I put into reading, going to office hour just doesn't help me at all and I barely am able to finish any of the homework problems without looking at the solutions manual. I feel paralyzed, I'm past the self-admission that I'm just not good enough to be in this field but the job situation frightens me. I have zero-experience in working yet I'm in mid-20s. I have absolutely no families to seek legal-financial support as all my families are non US-citizens except me and the only thing that keeps me being in the university is the promise of a piece of degree paper which everyone around me tells me how it won't help me get a job at all. I think I'm lapsing back to depression but I need some advice other than my academic counselor who refuses to understand from my situation and give any reasonable advice that I am capable of following. I really need an advice that I can understand the realistic side of it because I just feel so hopeless just about everything. Should I even continue with this major and the current semester? and should I even bother continuing with this major in any foreseeable future at least just to get that diploma? I'm struggling to even following the materials even when I'm just taking 9 hours of credit.
