I was a young child of an older mum, does that count? My mum went into menopause shortly after having me. Anxiety was her worst symptom, or so she told me when I was old enough to understand. I had to be taught at around age 5 to get on a normal service bus to go to school and back again, including lunch times as I was terrified of school dinners.
TBH I wasn't aware of my mum being an older mum until I hit my mid to late teens. I wasn't the worst teenager, well at least I don't think I was. My daughter's partners folks are older than us by a good few years. So there are a few of you around and have all survived to tell the tale.
I'm sure you will cope and do just great!
