I just started biking again as an adult and I love it but I *suck* at it still.
First time out on the new bike, and I was doing great - till I had to go home because I realized I'd somehow cut myself pretty bad on one of my pedals ffs. And I didn't fall or anything, I have no idea how I did that. Then I realized I'd cut the other ankle on the other pedal too, so now I"m the Fred in the kneesocks biking around town until I get less bad at this.
Third time out, I dropped my chain spectacularly enough I had to take it back to my LBS.
I'm scared of going downhill - like, enough that I have been known to get off the bike and walk it. I'm also working on not riding the brakes when I get scared downhill, I know I'm doing it and I remind myself to stop it but I still have to remind myself.
I bought a Road ID because I'm scared that I'll end up in the hospital just from doing something dumb not even involving a car, like hitting a pothole wrong and waking up on the tarmac with broken bones.
And yet? Perversely I still love this and I'm already totally scoping around for my second bike.
