Stop bringing me food!! I’m grieving, not anorexic!

Ever since my grandpa died Last Tuesday, I’ve been getting phone calls, people have been coming over which I do appreciate and some people been giving me food. I mean I appreciate it but I wish they would stop! I don’t understand why people bring food when someone dies? It’s not like I’m going to be anorexic. My cousin asked me a rude question “How much do you weigh now?” Really that’s a rude question to ask.
I need to be alone, people won’t stop coming and vet and I need to be alone to grieve and I don’t wanna eat. I’ve been getting rude comments on here that I’m not appreciative. I am it’s just that I need space.
