<human>: Could you distill the essence of the text into 1-3 sentences?

I told my boyfriend I would come to his friends house party tomorrow night. I'm incredibly shy, very anxious in social settings and it's really hard for me to meet new people. They're all older, and know each other previously, and there will be about 15 people there. I also don't drink, I hate dancing and I know there will be a lot of drinking going on there. I'm arriving late, and I just need some tips about how to go about this! I don't want my boyfriend to feel like I'm just clinging to him the whole time, and I want some tips regarding how to decline if they start a drinking game, start and keep conversations etc
<bot>: first party, don't drink, how does an awkward shy girl socialize with a bunch of older people she does not know
