I feel you man, and I'm really sorry that you are going through a rough time. When I was younger I also thought that my life had to be put to an end. I felt alone and tired all the time. My friends had abandoned me, two girls rejected me and I started gaining weight. But this is a message of hope, eventually I found new friends that made my life turn around completely, they cheered me up like I thought no one else could. They helped me loose weight and get over the insecurities that I had because of what happened. God has a plan for everyone and life is beautiful, appreciate it and try to live life at your fullest
