Can I adjust my dentures myself some kind of way

No. I'd strongly advise against it.

There are some at-home reline kits but I've seen that they don't work as well and oftentimes people end up ruining their dentures.

If you need your dentures adjusted because of sore spots, it's best to see your dentist. Most times, they'll do the adjustment at no charge and can do it in the office. They need you to come in so they can pinpoint the spots that are rubbing.

I've seen many people destroy their dentures by trying to "fix" them at home. Leave adjustments to a professional. :)

Definitely go see a denturist or dentist and have your dentures adjusted properly.
