Men, how do you get past the late teens/early 20s phase of feeling perpetually lost/awkward/insecure (if you've gone through it)?

I had a suicide attempt when I was 22 that involved a heavy hit to my head and must have rewired my brain because after that I was really spiritual after that and now I just do my own thing and i don't really worry about how other people perceive me anymore. My younger brother who was six years younger than me, 22, killed himself in June. I don't know if there is a common theme about the age 22 but it seems to be the low point for a lot of people as they realize that their youthful ideas and energy aren't worth anything and they're a slave just like everybody else. 22 seems to be the age that naive innocence and wonder dies. But if you can survive to say age 25 when your brain is fully developed, then you just might get out alive and make healthy life choices. For those of you wondering about my suicide attempt, I jumped out of the passenger seat of a moving vehicle. My boss' moving vehicle. He had to call an ambulence for me. The two of us are still good friends.
