My father has always been very over-protective and anxious.
I'm in my 20s and I have a job that involves a 5 minute walk to the nearest train station, and then catching a train home. He has anxiety and because of it he won't let me catch the train home, he drives to pick me up. I find it really embarrassing and frustrating and have told him I want to go home via train during my lunch break, only to check my phone when I'm walking out at 5pm to see a text saying he's parked outside and is here to pick me up.
He thinks he is just being helpful and nice, but I find it suffocating. My colleagues are always inviting me out for after-work drinks and I have to decline as I know he's waiting to pick me up.
I went to a dinner with work once, I told him in advance I was going and I would make my own way home. My phone ran out of battery but I borrowed a colleague's portable charger and when my phone turned back on I had several missed calls and texts from my him and he was panicking because he couldn't get hold of me. It turns out he had been waiting to pick me up since 5pm, even though he knew I was going for a meal. He ended up waiting 4 hours and when I got in the car I got shouted at for not answering the calls as my phone battery was dead, he worried that something bad had happened.
It's not normal. I'm embarrassed even typing all of this as I know it's so weird.
