Been feeling like throwing up since new years what should I do.

On new years day I drank with some people me not being an avid drinker it hit hard. As people do someone wasn’t able to hold all of their own down and threw up. Me seeing this was not a good time and I felt like I was going to throw up so I left the room unfortunately that feeling did not. Since that night I have consistently felt like I was going to throw up, I am barely eating because I don’t want to throw up and eating makes me nauseous as all hell, I can’t walk around or do most of anything for prolonged periods, and i’ve been getting extreme headaches for the last couple of days. Should I just bite the bullet and force myself to throw up? Is throwing up even gonna work at this point?
