I am in my early 20s and I can confirm I've never felt like this before: anxious, clueless, emotional, with a pinch of avoidant personality disorder. It's weird, though, because I was so happy in high school. Well, they say it gets way better. Even though sometimes I have plenty of doubts, I decided to believe that "the pain that you've been feeling can't compare to the joy that's coming" (cit.). So let's try and see what happens!
I've never experienced real anxiety before my early twenties. Has this happened to others?
