Should I tell my manager I think I have ADHD?

I’ll try to keep this straight-forward. I [24F] have been at my current job for 3 yrs. Today, I received my 2nd written warning. This one had a deadline of 3 weeks to address presenting issues, those issues being I am unable to fulfill the requirements of the position. After posting abt this on Reddit, multiple people suggested I have ADHD. The ADHD assessment with my therapist was inconclusive. Now I need to schedule neuropsychological testing, which schedules many months out.

After learning I may have ADHD, everything clicked. All of my issues seem with work seem to be linked to these symptoms. I have gathered many coping strategies throughout the years that can and have helped, but never used them consistently because I subconsciously thought “I should be able to do without them”. I was wrong. Since understanding this, I have been able to implement these strategies, which have worked really well, BUT I still need to practice/learn more about what I need, and practice more paying attention and what else helps.

But look, its been three years. To put it very bluntly, i think my boss has been way to understanding while Ive tried to figure out what is wrong w/ me. I would’ve fired me a while ago, but she didn’t, and here we are. Do I want to be fired? No. Main reason? Income.

My job has a LOT of intricacies and, in the end, i think I would be better doing something else. But training for my position takes a rlly long time (everyone at my job has to train for a long time). I want to leave things as tidy as I can for them. Can’t do that in three weeks- too many priorities to address first.

Part of me wants to tell my boss I FINALLY know whats wrong. I now know what I need to do. BUT, if I mention the ADHD, I am concerned they then won’t be able to fire me bc of EEO (Equal Employment Opportunity). These people are very ethical. So, I’m heavily leaning towards keeping this to myself.

Pros to telling my boss I might have ADHD: - I MIGHT get to keep my job for now - Maybe accommodations? I have one which has helped - May be able to update procedures for my job, making it easier on the next person (and on my boss to train them)

Cons: - My sweet, already burnt out boss needs to deal with more of my b*s - They might be afraid to fire me in fears of being sued? (I wouldn’t but these people are very by the book/take the high road) - I could lose my job in three weeks

Some other points: - Im already looking for other jobs, and know i am to apply ASAP. - I dont want to be fired, but think another person would be best suited for the job. I just want to be able to ease that transition and these 3 wks won’t allow for that.

I dont rlly have time to fix grammar or do a TLDR rn. Sorry and ty for any advice you may have.
