I went from being a happy kid that smiled all the time, enjoyed drawing and had several friends to a pathetic adult with no talents, passion, creativity, friends or a job. Just a worthless and unlovable failure. And recently it's gotten so bad that I've started cutting myself and contemplating suicide. I just don't believe I have what it takes to get my life together, sadly.
I believe that you do, because you had the courage and strength to reach out here, express vulnerability, and have yourself heard already.
Who told you that? I know there's a lot of external pressure out there and a lot of social and societal pressure pressed down on us in general, but if there's someone that told you such things, they've already proven themselves to be unworthy of your trust or your attention.
In dark times, should the stars also go out? You are alive. As long as you are alive, there's still tomorrow and a future that can be better than today. I came from several very dark places, one after another. I lived long enough to see better, and I believe that you will do the same if you let yourself hope and continue to strive, comrade.
