Exact circumstances 2 days ago while attending a friends funeral. Haven't been around that scene with the mutual friends of my friend whom passed away. They were all going to local bar to mourn together and drink. I felt like a smuck that I didn't attend. But I paid my respects by witnessing the beautiful services and saying my goodbyes to her personally. If you are in jeopardy then leave now. They will not really notice you are there or not if they are getting intoxicated. And maybe the fact you aren't drinking makes them uncomfortable too. So just a thought that this is your life at stake as well. Maybe you can express to your friend that you love and care about him and to call you for a personal visit tomorrow. Good luck
