Wasted at work party

I got wasted at a work party and I just can’t face work tomorrow. I genuinely feel suicidal I don’t usually drink and I have very bad anxiety I just couldn’t stop drinking. I didn’t do anything crazy but I wouldn’t go home with my partner so she left me there and then I was just rambling on to people and I have no idea what I said I’m so ashamed and I hate myself, I can’t face work.
