Don't sell yourself short! A four year degree opens doors that otherwise wouldn't be available and the ability to communicate clearly in writing is always a must have. I know some people took classes on technical writing. Plus, if you put down on a resume any computer skills you have as well, that'll help.

Your degree would be useful for tutoring as well. There's a lot! It just takes some brainstorming and hunting - no matter what your degree really.

I hope you do something to celebrate your hard work. Not just doing school, but overcoming anxiety and depression to move forward and succeed. Doing college with a mental illness is no easy task (plus a family!) - you deserve every accolade :)
