I never got a job.

( VENTING) I've been really struggling financially. And i want a job. But i know i will never be able to work. I failed calculus 2 twice.. so i'm sure if i get a job , my grades will be horrendous . currently i am an international student and in my 3rd year. I've never got an on-campus job till now.. I have severe Social anxiety too, so i can't seem to work as a student tutor too. I have little to no job experience, so i believe that's why no one wants to interview me. my family is disappointed in me. and i am too with myself. what do i do? edit: i hate being mentally and physically ill
