How do I know if I should be tested for having OCD?

I've struggled a lot with overthinking for most of my life, but for the last year or so it's been a lot worse and I've been doing some research, and a lot of the things I've read about OCD really resonated with me.

The thought loops, thoughts feeling sticky, decision paralysis, compulsions, rumination, all feel like familiar habits.

However I'm hesitant about whether it's worth it to get it checked out. I'm not gonna self diagnose, I just want to know what pushed you guys into actually getting it tested
