Am i alone?

I use to be able to tell the differwnce between my actual thoughts and what my depression was thinking. I use to know the difference and be able to push it aside knowing it was nothing but lies. Recently though i cant tell the difference. Its almost like my depression has evolved. It has become a part of me. It makes making desicions difficult. Is it actually me thats questioning it or is it my depression? I just dont know anymore. I hope im not alone. I hope someone understands but at the same time i wish im alone because i wish that no one has to deal with this confusion.
