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 was in a very similar place for most of the past year, and I'm not entirely out of it. Some of those feelings have gone away, but others have not. I didn't get things back together by myself, it was the support of others that allowed me to start healing.
I hope things will get better for you, and this community (including me) is here for anything you need to keep going and start moving towards a better place. If you just want to talk, for someone to listen, people to play games with or whatever helps take your mind off things or helps you work through everything please reach out. That includes material assistance too.
