Losing My Sense of Self: Dealing with an Identity Crisis

lately i'm losing my sense of identity. i don't believe it's any kind of dissociative disorder—i'm guessing this is depression at work—but i feel like i'm pretending to be someone. i force myself to do normal things like eat and socialize and hobbies i used to like hoping that maybe i can revive my belief that i am a living person with personality and identity. i can list things i do, people i know, and even events from my past, but it all seems to not amount to any tangible version of myself. i feel so lost, unloved, and... not human. i miss wanting to achieve things, learn things, and become someone. none of it's there anymore. and nothing i do seems to even slightly bring those desires back to life. i miss... being me. am i so far gone? is this normal of depression getting more severe than manageable? what can i do?
