I'm always taking care of others, but who will take care of me?

I have good friends and they're supportive and great listeners when I go to them, but I also feel like I'm always the one checking in with people or asking them how they are doing first.

I feel tired. Everybody is scattered everywhere across the world, and I have nobody I can just go and hangout with.

People are nice enough, but I just feel so alone.

I'm doing a lot to take care of myself as best I can, but sometimes, I just feel like, who will take care of me? Why won't anyone ask after me? When will I be acknowledged?
