I can understand! The thing that separates introverts from extroverts, as you may or may not know, is that introverts tend to feel exhausted after spending time in a busy area (say, a bar), while extroverts will feel more excited. This doesn’t mean, however, that introverts cannot have fun in these places, just that they can stand it for less time.

However, your situation seems different. What frightens you about the bars/clubs? Is it the new people? The social “obligations” (dancing, drinking, etc)? Is it the fear of becoming over-exhausted (this actually affects my own enjoyment at parties. I get stressed out because I feel afraid that I might get too tired, especially if I have a busy day the next day)?

I would suggest going with your friends, only if you feel comfortable. Then, when you’re there, try to eliminate the thing you feel makes you uncomfortable. Baby steps, you know. Don’t drink, be the designated driver! Don’t dance with people you don’t know, if that’s what frightens you. Or, hang out in the back, and watch other people dance/drink/make fools of themselves, then join in when you feel comfortable. That always helped me out!

If anyone else has any ideas, feel free to discuss!
