I wouldn't say there is anything wrong with you. And define "normal". You are who you are whether others would define it as normal or not.

Sounds like you are in a phase of figuring out your identity. That is a difficult period. There are all the ways your parents think you should be and then all the ways your friends think you should be, and what society thinks. Really it is totally up to you. Be who you are. Decide which things you would like to change based on what you want and not outside influences. Self acceptance is huge but we all have things we want to change. Not wanting to go clubbing and drinking is rather mature and nothing wrong with that.
