And, if so, how did you handle it? Do you regret any decisions you made as a result?

well my friends advised me to start going to the gym, now im not much of a gym goer, so they keep bugging me, you can get helpful peer presure, like ive had in the past, but if you dont want to do it, you dont have to

yup i been in this... Bt nw i m happy ... Thnk god i survived....

@james85: Very good point! I hadn't thought about positive motivation.. that is a form of peer pressure, just the flip side :)

Oh many times, and I didn't always handle it well. I don't regret it, because it's to late to regret it now. It's long in my past.
Though the most recent ones I have been a 'victim' to were positave things. One was joining my sorority, which I do not regret at all, I love those ladies dearly.

@mrb89: That's awesome! I know what you mean... but most of the time, when my "friends" urge me to do things, it's not for my benefit /: //sigh//
