Appetite gone 😞 Existential crisis

Hey folks. I have depression and am on 80 mg of Prozac along with an array of other things for anxiety. I have just realized today that I haven’t been eating. I cook for my husband and he eats without me. I haven’t eaten in 3 days. I drink enough water so I know I’m not dehydrated. But like, wtf. I don’t necessarily feel sad, I’m just not hungry. I’ve also been thinking a lot about non-existence. (Paradox, I know) I have a husband, family and pets that love me, but I’m just feeling unfulfilled. I’m not sure why I’m here, like on this earth. Why is anybody here? Husband says it’s to love and procreate. I just don’t understand why.. Has anybody felt this way? I don’t know how to pull myself out of this funk and honestly, I don’t even know if I want to. It seems like the worst part of my day is waking up, but I know I have duties to fulfill. I don’t look forward to sleep because I never have pleasant dreams. I’m sorry for the long post. I’m just... tired.
