That's the feeling I get every few hours, when I focus on everything that I've done wrong. I had so many opportunities and I threw it all away. I'm so stupid. I can't even manage to kill myself right. I'm a loser. That is all.
You're not stupid & you're not a loser cause you're not the only one that feels this way. Even I feel that way. I've made a lot of mistakes that make me just wanna tear my hair out. You're not gonna be able to do everything thats "right". You're only human. You'll miss opportunities and make mistakes but hey.. All of it just may make you wiser someday.
