Does anyone else feel disconnected from who they were before they had a mental illness... like that was a different person?

I’m not sure there was any clear definite line where I didn’t and then did have mental illnesses. It’s something that has been there as long as I can remember, in different ways.
I do feel disconnected from myself as a child, and even from myself now. Part of that is because of mental illness, but not because it was absent before.

yeah

Me and my anxiety/depression are two different people.
