I also forgot to add some helpful advice for partying.
At parties, if you don’t want to drink, buy Gatorade, Powerade, non alcoholic glass soda or juices bottles, or powdered mixers that you use for water bottles. People usually bring these drinks into parties all the time. You can also pour these drinks into an empty red cup and pretend that you’re drinking. Just make sure that you always hold your cup and don’t place it down anywhere. For the glass bottles, tear off the labels and no one will know the wiser. I did this at parties with my old roommate and it worked out well for us. Most people will never get curious of you if they see any of these drinks in your hand.
Even if someone does find out, then don’t make a big deal about it. Just be honest with them and leave the party if they give you a hard time.
