19? And feel like a loser? I can relate - but then I also felt like a loser at 23, and at 26, 28, 30, 32, 35, 38.............59, and at age 60. I took a year off from university and worked construction, bounced at a local bar, and drove truck. After a year, I felt that I knew what I wanted and started working towards it. It did not mean there weren't struggles or failures (lots of failures), but I just kept going. Eventually I made it to where society would consider me a "success" by finanical standards. I still think about CTB but now I have decades of experience behind me to say that things did get better. At least now one has the internet and sites like SaSu. No matter how many therapists I saw over my lifetime- and I tried dozens - not one allowed me to open up like I can on this anonymous suicide discussion board.
And to be clear, I sort of found myself after a year off, but if it takes others more years, so what? Everyone has a different path. I was never going to be the boy wonder of anything but I am easing into the role of senior statesmen in my profession. Hell, that just means mere survival can lead to success. Look, my opinion is not woth anything, but I believe that that the mere fact you are asking yourself these questions proves to me that you can find the answers. You may just need some time away for the "noise" of life and responsilibity to hear those answers.
