What? Please don't! I feel that way too a lot but, please don't! You should love yourself enough not to, you wouldn't kill someone you loved, would you? Try what I try instead: go to sleep. Get a good, long rest. When you wake up, maybe things won't seem as bad. It's a less permanent version of the same thing. If you're asleep and you don't like it, good news: you can wake up. If you're dead, you can't just come back. You're thinking of it as a solution, but just imagine how terrifying or horrible it might be. :(
