First timer considering college again after dropping out first semester 22 years ago

Hey guys and gals. I've just learned about Sophia a week ago and I'm seriously considering trying it out. I tried college straight out of highschool and dropped out almost immediately. I'm pretty scared about taking this leap but having a degree would definitely better my career (InfoSec).

The general classes are the ones that freak me out the most. I have anxiety and ADHD but I'm in a position where I can 'work' and do Sophia courses during my working hours before grabbing kiddos after school. Has anyone else been in this position and how hard are the actual courses? How hard was the transition to a regular college to finish up the degree? I feel like all the terminology for getting into a school is also playing into my anxiety because I don't understand how it works and I don't want the peer pressure of sales calling me trying to get my enrollment.

Any tips or insight anyone can offer would be highly, highly appreciated.
