You seem to be overconfident in your abilities but lack follow through and organization. You skip class, you plan to make up half a dozen assignments at the last minute, and your backup plan is to just redo courses over the summer. If you were my kid I’d tell you to get a job for a year or two and return to school when you can prioritize your work, meet deadlines, and show up when you’re supposed to.
If you need help getting your anxiety under control please see someone.
