I'm sick of being a loser at everything?

I'm tired of failing everything I try, I graduated high school in 06 and kept failing classes in community college and changing my major and got on academic probation, then suspension. I left and started selling cars for 2.5 years. My manager convinced me to go back to school, first semester back I needed a 2.0 otherwise I would get academic dismissal I tried as hard as I could still fail 1 class and now I don't know if I can appeal the dismissal. I wanted to withdraw from the class but family heath issues happened so I was distracted.

Apart from that I'm 26, living at home, and never had a date.

What do I do, I haven't even told my parents.
