Hello I suffer from a mental illness and its getting worse and my behaviour and reward system is more akin to a dog then a human. Can you prove me wrong with acknowledging the dog or illness even exist?

If you can, is there anything wrong with me using the same logic to prove I am a dog?

Its a simple but silly idea but it is incredibly powerful. I was told for years I did not have an illness until I became incredibly ill. I am beginning to start to piece it together. Any thoughts?
