Your list of possible directions exemplifies the diversity in topics that are all exciting to some people, but are meanwhile completely uninteresting to the average person off the street. In fact, the same person who can't stop thinking about A doesn't necessarily like B even if they're next to each other on your list. In this post you're looking for someone to tell you something to feel that passion about, but honestly: good, actionable advice would require the advice giver to know you personally and understand what sorts of things would have that sort of pull for you. Any specific answers to this question from strangers will be shots in the dark.
So with that, is there anyone among your close friends and family who you could pose this question to? If so, that should be your next step. If not, you've got the tougher challenge of asking yourself. Why do you want to address either of the problems you've outlined? What is captivating to you? These are very personal questions and deciding "none of the above" is perfectly valid as well, you might just need a break from CS. And that break can be indefinite or even permanent. Fortunately it's clear that you're introspective here and that will be an asset in figuring things out.
If it would help in any way, feel free to reach out directly and I'd be happy to chat. I just made sure my profile here points to contact information.
