I'll second this. I spent roughly 2/3s of my life in a terrible ADD vortex of self loathing, hiding, and genuine depression. My sense of self had diminished to a scary degree towards my thirties because I was convinced I was a broken person but had this job to upkeep, kids to raise, a relationship to maintain. I had given up on understanding what was wrong with me.

Then I realized my kid had an attention disorder and decided to research it. I realized I fit the description as well. I discovered this is often passed from parent to child and I had no idea how to navigate this myself or how to help my kid... Who I gave this thing to in the first place.

In the short years since I figured this out, talked to professionals about it, and generally started setting myself up for success instead of living moment to moment running from failure... Things have changed such an incredible amount. ADD will never go away, I'll always be like this, but now I have some sort of foundation and understanding to work from. I'm motivated to overcome it so I can help my kid, too. There's no way he can have the experience I did.

It's so worth talking to someone. I suspected something was wrong for 10-15 years and never did anything and I seriously regret it. What if I had an extra ten years of being aware of this thing? Would my family be happier? Would I own a home already? Would I be happier and have better self esteem? Probably yes to everything. Don't delay, take care of yourself.
