(((((lost4words)))))) Welcome to PC.
I would seek out professional help. Your local doctor would be a good place to start. I would print out or right down what you have written in your post and share it will them. Your doctor my what to run a test or two to make sure that you are not having some kind of physical problem. They will also be able to point you in the direction of a therapist.

It is important that you eat and drink. I went through not eating also. My therapist told me to put out munchies that I liked with a bottle of water, set them somewhere that you see them. In time you will nibble at your munchies without really paying attention and they will be eaten. It is very important that you eat. Good luck, keep us posted, hugs for your day.
