We all feel pressure from temptation, but sometimes even moreso from our peers.  It's important to remember two things: 1. If/when you mess up or give in, that doesn't end your life.  Learn from it and move forward, better than before. 2. Anyone pressuring you to be someone else or do something you're not comfortable doing...they're not you.  They won't live your life or deal with what you deal with for consequences.   Be you.
