I’m never hungry after my breakup?

So for the last four days now, I’m just never hungry. I forced myself to eat at first, but I gave up because it just made me feel sick and nothing tasted good. I haven’t eaten in over 24 hours and I feel fine without eating. I guess this is the part where I should mention I broke up with my boyfriend four days ago because I found out he had two other girlfriends and a wife. I’ve had a lot of breakups, ngl, I’ve had worse breakups. But since that day I just feel numb and I don’t feel like eating anymore. Has this ever happened to anyone else? What do I do?
