Hey, 25 is still young! keep up, hang on - live doesn't end when you are 25 :-)
I'm 32 no and I haven't achived half of what I planned when I was 20. I got my diploma 2 years ago, but only a mediocre on. I'm unemployed for two years now and just started a therapy because this drives me into depression more and more.
A friend recently told me that we all go through this phases. We have to struggle to gain a new standpoint, perspective and a new aim.
