I haven’t eaten properly in around 4 days now I’m very dizzy and faint and have to sit down often
Yesterday I didn’t eat because I felt off but nothing came of it and and today I bought a cheese pizza that was supposed to be cooked from frozen but I put it in the fridge by accident for around an hour I cooked it and burnt the crust and the toppings were bubbling but still couldn’t bring myself to eat it what do I do
