some confusion and problems?

[ÅrcaneMage]

I've noticed that since I've opened up to a few things that I've been having emotional conflicts with things I would have never questioned a few years ago. I feel now as if I'm irritated by my former self and older friends, I started working outside of my small home town, made a whole group of new friends and I seem to prefer them to all my previous ones. even my (not blood) brother, I can't stand how immature people act around me. We used to play a game called spirit lifting, when you walk past someone thrust your finger over there nipple (catches people off-guard sometimes make them laugh) but now a day's I can't stand my friends touching me. (I brought that game to our town) is this BECAUSE of what I've been doing? Is it something common? Has this happened to you? How can I reverse it? anything you think pertains to this feel free to add.
