I dropped out in 1971 for reasons similar to yours. I am now retired. I've supported myself by writing software since the 1970's.

Dropping out has cost me several hundreds of thousands of dollars. I don't know how many. Lots of companies pay more just for having a degree.

Consider transferring to a cheaper and/or easier school. You'll have more time to yourself, which is often a good thing. Unless you're actually depressed.

If you're interested in CS, math is almost always useful. I wish I'd had more. Most of the topics you list are research topics only available to research-level academics.

Changing schools is the one thing I regret not trying. Another thing to consider is to change girlfriends. Or find a better one. That can certainly impact your overall view of life. In other words, don't ignore the social aspects of choosing a school.

In the 70's through the 90's I had to contend with management that was often quite stupid. And quite often did not even know what a computer really was. You can avoid situations like that more easily if you have a degree.
