Interacting with others high on drugs

Im currently at a get-together with family and im on a little bit of coke. I'm a bit anxious because I know my uncle is in AA and that my mom and i currently don't have the best relationship. And my relationship with my brother is a little complicated at the moment. I've never been in a situation where im high and surrounded by sober people. I currently can't get sober because i don't live alone and i don't want anyone to know that im doing drugs (trying to quit tho).<br><br>Does anyone have any tips for me? or can you guys just words of encouragement?<br><br>TLDR another family get-together and me high on coke again<br><br>EDIT:<br>Thank you so much guys for the support and encouragement. I'm fine but i already have my AA sponsor on speed dial so you guys are my closest friends currently
