How Is Covid Coming Back?

I get that variants are obviously different (hence the name variant) but I didn’t know if it took care of the basic structure of Covid, meaning the variants would be protected from it too.  

I got Covid and I’m glad I was vaccinated because it was still hell, so I can’t even imagine getting it before the vaccine.

I get what you're saying. Even though vaccines might not be for the newest variant, they do still help because they're the closest to the currently circulating variant (generally speaking). On a biological level I'm not sure how COVID is changing over time but the concept in general is called "Antigenic Drift". So if you want to look more into the concept you might try looking up something like "COVID Antigenic Drift"

Imo it's still a good idea for people with weakened immune systems to continue to get the vaccine even if Antigenic Drift does lower it's efficacy over time.
