It sounds like you're putting yourself up on a high horse, not really searching for enlightenment. You're 17, just live it out. You're pretty good at writing, have you considered doing that with your life? Freelance writing or something? Point being, you're not going insane, you're just 17. Pretty much everyone goes through this.
maybe you should stop dwelling on whats "wrong" with you and start seeking out what is "right" with you...
seems like something i'd do. i ask for help then feel guilty about doing so. trust me on this one.. BE SELFISH WHEN IT COMES TO YOUR MENTAL HEALTH! i'm giving you permission to do so. if you ever feel bad about asking for help, just remember: booga said i can, so i'm asking!
please post the thread again because i think i might know what you are going through. Im only 14 but for about a month i truly thought i was going insane and i was so convinced. I think i went through what you are going through now
