Drank a lot of alcohol on sertraline, now my mental health has plummeted, is it because I drank?

Saturday night was my jobs Christmas party and I lost at beer pong, got absolutely hammered.

I've been on sertraline for almost two years now, I rarely drink if at all, but now 5 days later I feel incredibly depressed and slightly suicidal. I haven't felt this way since I've started my meds, they really help me with my depression and OCD.

is it because I drank so much? Will the feeling go away?

I'm also iffy about my relationship with my boyfriend right now, so I don't know if it's that making me depressed or what.
