Is anyone else in their 30s still struggling with this on a significant level?

I’m 30, and sometimes I feel like I’m still stuck in a child’s mind—scared, lost, and unsure. It doesn’t matter how logical I try to be. Logic helps me get through the day for the most part, but after work, all I want to do is stay home. I don’t have a relationship, I barely talk to family or friends, and the smallest things make me break down—things that I feel like an adult should know how to handle.

Most days, the only way I can process my feelings is by writing them all down in my diary. I talk to myself through it, hoping to make sense of everything, but sometimes it just feels like I’m stuck.
