I Am Not What People Expect

I think I lost my identity when my mom passed away. I don't know who I am anymore. I lost the urge to keep going. I lost motivation, the determination to get what I want. It feels like I just wander around with no particular destination. I just go with the flow, without even realising if it is good or bad for me. I can't even decide for myself, I let other people rule me. I feel like I'm just living for the sake of surviving into this world. No purpose, no goals.
