Tips for an introvert going to a party?

I've been invited to a Christmas party in 2 weeks but im a really introverted person. las time i went to a party, all i did was sit in a corner playing on my phone. my friends who are going are forcing me to go and honestly i want to go because i want to socialize more. i dont know how to do it tho. i dont know what words to say to spark up a conversation and how to keep a convo going without it being awkward (mainly with girls). Also what are things to do at parties?

Any tips on how i should act? and should i drink alcohol to be more outgoing?

any tips helps! especially those from a girls perspective
