Take a nap, have some vitamin C, vitamin D, vitamin K, and some chocolate or dry aged cheese(both can jumpstart serotonin depending on the person) every day. Avoid the phone and internet for a few days. Talk to some people you trust about what you are thinking, and see how you are feeling in a week or 2.
I mean, everyone know about depressed/heartbroken people eating ice cream crying in front of tv, trope right ?
Well, in fact, there is valid scientific reason for that and why your body try to "eat".
Bc eating (especially sugar) secrete dopamine, hormone of happiness, hence counter balance the stress/sadness.
tldr: body try to solve the problem in its own way (not caring about weight)
