I'm like this. I have ADHD though. Find it very hard to focus on small talk NEVER bloody remember what They've said and feel drained.
Same (I'm like this and I have ADHD).
This all sounds really similar to me. I always worked full time so never did the school run, then when I started WFH I had to do it and it's by far the toughest part of my day.
Afternoons are slightly easier because I have to do it, but mornings I do everything I can to avoid it. I take my kids (6,10) as far as the road crossing and watch them go into school themselves. Covid has been a blessing with staggering pick-ups, so I pick up 10 mins after the first / before the last possible opportunity and avoid most people.
I'm not rude. I'm honestly very sociable and can chat / listen to rants / make small talk, but I struggle on the school run. There is just far, far too much going and masks add another layer of stimulation. Weather, people, masks, children running around, cars on the road, younger children crying, avoiding that person with a buggy, I need to go to Tesco for milk please don't forget again, I left that work thing unfinished oh shit, did I leave the dryer on, child pulling at you, another child getting in everyone's way, am I getting in everyone's way?.... and then someone starts talking to you (about nothing of interest, usually) as well. It's really hard to explain but it's a very physical feeling of being uncomfortable. I can feel myself irritated. It's an exhausting mix of brain fog, annoyance, anxiety and overwhelm.
We used to joke about this in my family and call it "the grandpa gene". He was / is what you'd call "highly strung". I.e kids being kids he could cope with to a certain extent, even embrace, but then he'd just not be able to cope anymore. Too much noise or mess or stress or movement. I am like this unmedicated. I can be in a foul mood for no real reason, or happy to the point it probably looks manic for no real reason, or irritated or amused etc with very little cause. It was only years later we realised it was probably adhd with my grandpa, and he'll have given it to my mum who passed it on to me.
OP is there any way you can drop at the gate? That's the only thing that makes mornings bearable for me. Pickup, the 10yo makes her own way and has done since she was 8, and in non-covid times I'm on the polite side of late for the younger one. In and out.
