I have no identity

I can't speak to the cultural, gender differences, but anhedonia is awful. It's not just a loss of interest. It's a loss of everything that makes you feel something.

What helped me was a emotional support dog. He is little, so he stays inside. But, even if I am not doing anything or going around anyone, having him beside me just helps.

The other thing, just do it. If it's binge watching a show you like, do it. If it is going out with an old friend and you don't want to really go anywhere, do it.

It's actually pretty intelligent to recognize how your depressive state is tied to lack of identity. We all crave psychic wholeness and imo situations like yours scream out for the individuation process of "who tf am I?" I'd say that 90% of non-reactionary depression cases stem from lack of identity or self-congruence from humanistic psych where the internal & external don't align. I was in the same boat once and I'd recommend reading a ton of Carl Jung, Rogers & Maslow, and Adler. (They r slightly different in their views but understanding concepts like self realization & actualization r imperative) I have ADHD brain so I was lucky that I found someone online who studied humanistic & analytical psychology who could explain it all to me instead and it clicked in the first 5 minutes.

I understand how you feel. Depression can definitely ruin your mood and destroy any motivation that you have to do the things that you need to do. Then it gets overwhelming because it doesn’t seem like anything can be done about it that is within your control. Have you tried therapy and medication? They’re not always a perfect solution but they can help. Sometimes it just takes treatment and time. Can you talk to your parents or do you have any friends there for support? Reach out to others like you’re reaching out to us. Don’t give up on yourself. You have no hobbies, interests, or goals now, but maybe if you get treatment and force yourself to try new things, then hopefully you’ll start to see some changes. I know it’s not that easy, but I do really hope that things start getting better for you.

I have interest in nothing

Find something that does interest you. Something creative maybe. I've been pretty depressed and without any meaning until I rediscovered my love of writing. The internet is a vast place. Pick up a paint brush or a pen or something and create. It'll give you a great sense of purpose.

Doesn't have to be creative though. Do something you enjoy, like watching TV, go to a bar or club. Sing, dance (I dance alone in my room), play a video game. Find something that interests you

Start drinking coffee. It makes you alert as much as you want. I know it is impossible to become motivated enough while heavily depressed. Coffee was my miracle. As a man I even couldn't get my exercises benefits while I was heavily depressed. It effects you that much. Right now drink some coffee and see results. It will turn you into stressed, angry but living kind of loser, far better.

Yeah...it sucks. Having interest in nothing. I felt life was empty and meaningless. But it'ok. It's a symptom of the illness. Have you sought any treatment? I would start there if you haven't.
