ADHD Assessment tomorrow, but is it even worth it at this point

I’m 24M, and I’ve had ADHD my whole life but I never got it diagnosed because my parents didn’t believe in it, even when my teachers told me to get me checked for it. I’d like to thing I did pretty okay academically, as I was able to switch from pre med to SWE and get a masters and full time job in it (trust me, it was not easy as I had many failures and dissapointments throughout with procrastinating.)

The reason why I’m getting tested now is because s because I just got dumped a few months ago by my first girlfriend. A lot of the problems I caused was from me being unable to shut up and not say something dumb, poor emotional regulation, and just not being mindful of her feelings along with being stupidly impulsive with my actions / words and RSD. I also looked into more of the social aspect of how ADHD affects it and realized that I resonated with almost a lot of those things listed. I also have executive dysfunction in my personal life regarding cleaning my apartment, losing things, etc.

It’s gonna be $1000, and I don’t know what type of treatment or meds they’ll give me. I’m wondering if getting tested And spending this much money is worth it just for the social and life aspect, I have trouble focusing on my job sometimes but I still manage to finish things, even if it’s a little late. I also see that many people get side affects and lose their personality in it, which is another thing I’m scared of. I’m trying to see if the benefits will outweigh the negatives of getting diagnosed.
