I have friends with adhd tell me that I have it, but my parents have suggested there was nothing present to indicate I had it as a child, which seems to be a binary input for diagnosis.
But I do seem to way overreact to the silliest things. For example, if my toddler trips and falls, my mind immediately races to "they definitely knocked all their teeth out and will be in pain and will have dentures forever and will never enjoy life again", and that seems to short circuit my reaction into a total panic/meltdown before I've even looked at the kid's face (which never hit the ground). And the advice of the internet such as deep breathing, stepping away, etc. is totally unhelpful as it seems my reaction is instantaneous. Then there's the crash and shame that follows it once the initial surge passes, which feels like my brain is lurching forward in my skull when I can feel it happening or stop it. And then I vow to never do it again, but then it happens.
I seem to mostly exist as a normal human otherwise. I can hyperfocus on coding, but that could just be normal focus because that's what I do all day.
My suspicion is that I have depression since the symptoms are overlapped, and I've never scored below a 20 on the phq-9.
Recently when I've crashed, I've started considering seeing a psychiatrist, but my motivation seems to run out quickly after I start considering it or looking them up. I also don't want to be involuntarily detained and lose my tsa precheck.
Edit: Not sure this is relevant, but I do tend to hit/slap my face when I get in these overwhelmed states, which my wife has pointed out is not normal nor okay.
