Hey, i'm in my 20's also :)

It may seem normal to you and not a big deal since you kind of dismissed it but you did describe a childhood full of turmoil (gangs, drugs, parental issues). You might want to talk to a mental health professional about these things. Your childhood environment could have made a negative impact you're not yet aware of.

Other than that, try focusing more on doing things you believe is useful to the next generation. Feeling valuable to the next generation is hard wired into humans but often times ignored causing the well known mid-life crisis. You may have just gotten there a lot faster than the average person.

The things you do to aren't important it's the way you think about what you do. For example, most people do this by raising kids and feeling responsible for the process. Another option is to become a mentor to one/many people and share your wisdom and experience with others. Pretty much anything works even things generally considered superficial as long as you believe internally you're doing it to serve others.
