Help Planning Ahead

So how should I start?
I’m a senior that isn’t going to school at the moment due to a worsening medical condition, and because of this I’m looking into going to an outpatient clinic for the time being (for no longer than a month or two I hope).
Although I should probably put all of my energy into the present, I can’t help myself from worrying about what to do after high school.
I’m already planning to take a gap year since I do not believe I am ready or able to give college my all, but after the gap year everything becomes incredibly blurry.

Before I go pleading for help about my future college life, I’m guessing that I’ll have to communicate what kind of credentials I have.
To make it short, almost nothing. My GPA is like a roller coaster, usually being quite low. Right now it’s sitting below a 3, and will most likely stay that way by the end of the year. I’ve also done zero extracurricular activities, not even a single sport. The only thing going for me is a 34 on the ACT without the writing. Although it’s a decent score, I do plan to retake it sometime during my gap year since I know I can do better (I didn’t study), and I want to do the writing.

Take note that even though it may seem like I have no interest in academics, I really do, and I really want to go to a college that can help me flourish.
So if anyone has any recommendations I’d really appreciate it.
I’m interested in physics, biology, and video game design. I’d like to major in video game design if it’s available, if not I’ll happily take computer science.
I know I can’t be too picky, but I’d rather a smaller school with no apparent religious affiliation, and at the end of the day I just want to be surrounded by smart and interesting students and professors.
Maybe more choices will be available if I can transfer from a community college, I am ignorant on the subject.

Thank you so much for your time, and I hope you have a good day!

I just want to tell you about my recent experience with CC. Mine is a vo-tech. I was very surprised. Yes the other students are all over the place ranging from brilliant to very disadvantaged. Many older students, (like me) many former military going back to school. Super diverse.

However the teachers are really into it. Some much more qualified than I expected.

There are lots of resources- academic support, financial support. They are used to people with complicated back stories. There are a few clubs(not many). I know the social part wouldn’t be the same as living in a dorm.

It is cheap and friendly. Mine has plenty of parking. I have found the whole experience much less intimidating than I expected. You can register pretty late . Certainly something to consider after your Gap year. You could transfer out to a 4 year school or you could learn a trade. Computers, x-ray tech, nursing, electrical etc…
