I thought my life was over at 22. It wasn't, i'm 28 now and I still feel young because I kept putting on sunscreen and took meds for my hair loss. Honestly, if you think it's too late to socialize, here's a reality check.

It's really only TRULY over when your peers start having kids, that's the real answer nobody is telling you guys. That's when it's over, and you're lucky you live in a world where the average age to have a child is 30+. You still have plenty of time to make friends and have memories, and if you think "oh I should've started at Y age"; trust me, you'll wish you started now. Because having good times starting now really does make up for the lost time in the past exponentially, and you begin to forgive yourself. Then realize the people around you didn't have a perfect time either. And the people you thought had a perfect time end up falling into turmoil (great early adulthood then ruined with divorce/depression).

A family friend of ours seem to have it all, he went to an ivy league; go into an accelerated medical school program and then he dropped out and now he completely isolated himself at 31. He's an only child and his parents don't even go to events anymore. If that helps when you think "oh other people are better than me", you never know when shit hits the fan and it all ends, what good did your past experiences do then? You're just supposed to be on the uphill, and not think in absolutes.
