Can anyone give me tips on dealing with my fear?

Pretty much all my life, I’ve had a fear; but only now I’m a teen it’s surfaced and influences me every day.
For the past 15 years, I’ve lived in the British countryside and been raised, I guess, a little differently from people my age. We’ve been pretty isolated and so forth – at nights, I never went to play out with my friends, or go out to the cinemas with them or anything.

The fact is, I’m a bit of a dunce when it comes to public transport. I’ve never had to use it, and now it seems a bit of a phobia has developed. My friends are always inviting me out, but I really don’t want to go because I’m afraid of getting on buses and trains and the like. I guess it’s because I have no experience of those things.

Anyway; it’s really very embarassing for me to talk about it, and I can’t tell any of my friends because when I compare us, they are completely adjusted to those sorts of metropolitan concepts and I know nothing.
If anyone could give me any advice or methods of dealing with this, it would be great. I have such a lack of confidence and personal strength when it comes to this!
