Hey man,
Late reply, but...

What's wrong with me? Can I still grow as a person, or is it too late to change something? One gets the impression that part of life has gone nowhere ..
This is essentially the male mantra/motto, don't communicate, accumulate stuff, be dependable and reliable, hush and... I feel dead inside!
I would suggest at least being wary of electronic communications, including here to a degree. People can be at their worst when hiding behind a computer screen, though some believe that people are being honest. Fair enough either way.
The main thing is it isn't what we do, or achieve, it's about do we enjoy any of it along the way. It won't always make you friends if you put your emotions over being an ideal rock of a person (though some people will respond positively), but the only one who will be missing out on life is you, if you don't allow yourself to feel your emotions.
Easier written than done, but there is whole other world there to be explored. It takes time to unlearn a lifetime habit/practice of shutting down our own emotions as guys.
