Hi,
I'm 26 too and I know how you feel when people tell you you're "too young" not to go out. At our age it's almost expected and its definitely one of the harder parts about trying to stay sober at our age. My only advice is to try to find friends whose idea of "going out" isn't getting wasted. There are plenty of fun things to do without drinking. I used to think that it was normal to get drunk everynight at my age. But the more you branch outside of your social group the more you find that most people actually don't feel that way. It must be hard being in a new country and trying to stay sober, but at least you have the chance to start completely over and find friends that can support you rather than trigger you to drink. Good luck with everything <3
