Drinking/consuming alcohol isn't good to do when struggling with depression or anxiety for that matter. While the alcohol increases dopamine in the brain it also makes it harder for that area of the brain to produce dopamine "naturally". It's important you pay attention to how you respond to drinking alcohol, passing out at a party with strangers is not safe even if others at the party happen to also be consuming alcohol. It sounds like you had too much alcohol and too much is something that depends on the person doing the drinking too. Well, you passed out and then ended up waking up and it sounds like you experienced a depressed state which is why you ended up crying in front of strangers that just did not understand the chemical behavior you were exhibiting. People can be rather stupid about how they observe others who drink who might not really be able to handle alcohol all that well. Everyone is different in how they might react to alcohol too and when someone has depression or anxiety once the alcohol wears off they can feel even worse and be extra depressed and some who drink can get angry and say mean things they later regret, that is if they can remember. Younger teens and young adults often think they need to drink alcohol to fit in, but the truth is you really don't HAVE to go along and consume alcohol some people just can't drink like others seem to be able to do and it's really ok to just drink a coke and not have any alcohol. I know for myself I was what is called a cheap drunk so I would only drink a glass of wine or two and then switch to coke or tea, I never wanted to get too drunk or pass out and be so vulnerable like that and besides no one wants to be a "sloppy" drunk, especially if you are a female. There are lots of people that go to parties and have a nice time without drinking. If you struggle with depression then you should look into antidepressants, and if you are already using an antidepressant they all pretty much warn about not consuming alcohol while taking them. It's really up to you to learn how to manage yourself with what you can handle and what you should not do. Take this experience as a lesson of what NOT to do for yourself next time.
