I don’t think I know who I am anymore

I just don’t know ,everything is gone I don’t know what I even like I just put up with anything, I don’t know what I want. Honestly when I look in the mirror it’s doesn’t feel like it’s me it feels unfamiliar it’s weird. I feel like a walking corpse. I used to like things I used to want things I used to get excited over things. If someone came to me right now and gave me 1 million I don’t even think I’d smile, I’m just blank
