What do I do

Last night I went out with friends to the bar and after getting drunk I had an emotional breakdown. I don’t know what caused it or what’s going on but I feel horrible. This never happens and I been pretty happy the last couple of months. It was completely out of the blue I got mad at my friends about something but when I asked them today they had no idea why I reacted the way I did. I don’t know what to do I feel like it took a hard toll on me and I’m scared it’s going to happen again. I woke up this morning still crying and when I try to explain it to anyone it triggers me.
