I would say if you are struggling to just let it go and revisit school when you are ready. I have had the same issues and it was never worth it to continue until I was in the right headspace for it. I still have no degree and wish I didn’t force my self to attended classes. I have a decent job not where I want to be, in IT as well but POS side. Experience has gotten me farther than the classroom. Are you sure finishing will be financially beneficial?
