People with ADHD often tend to have more anxiety than “normal” people.

No, just because you have anxiety doesn’t mean you have ADHD. Nobody is trying to make this argument.

Try living a life where you remember far too late, and it happens far too often, that (something) needed to be done. Here you are having a regular day and the phone rings or a text message pops up and (insert “oh shit” here: missed your appointment, forgot you were working today, missed a class final or major assignment, a late bill, missed a deadline, etc.) because your ADHD spaced it out completely. And it spaced out putting the pop ip reminder in your phone. Or of you put it in, your dumb ass silenced the phone. Or you didn’t remember to make it an audible notification and hour beforehand. Or any number of opportunities you had to put barriers up between yourself and a fuckup that you just never did, or sabotaged yourself somehow, because ADHD. After years of getting painful or costly reminders of your fuckups you tend to get a ptsd-like anxiety where you will be just being alive and suddenly get anxiety because you remember the last time you were having a good time something jumped out and reminded you that you forgot it and fucked up, and you’re sitting there wondering what you fucked up even if you didn’t fuck up just because you know that last time you were happy you fucked something up by forgetting. And it was too late to fix that thing, so you were incredibly stressed wondering how you’re going to unfuck it, if you even can.

That’s anxiety from ADHD. That’s when ADHD is a real thing that negatively impacts your life. No, not just an “everyone gets stressed if they forget”, it’s you knowing you’re going to forget, trying to remember to not forget, forgetting all of that, then paying the price for forgetting over and over again.
