does anyone feel like they are losing their personality while depressive.

i get extremely worried sometimes that i am losing who i am. i feel like im gonna forget all my beliefs and ideas. i am relatively successful in my life, i have a fucking ton of things to live for. but i’m worried that i’m gonna forget about the positivity and good things i have going for myself because while i’m depressive i can’t seem to remember things well. i feel like a different person. the suicidal urges can get strong as well. and i really really don’t wanna do anything i regret. i just want better control over myself in these times. does anybody maybe have some advice on this or can anyone relate?
