Probably. I tried to kill myself several times between the age of 11 and 18 and all I can say to you is: hold on! life does get better, whether you'd like to believe it or not. There's always sunshine after the rain :)!!
I'm sure many, many have...if not worse. You realize you are worth it to keep going. You have a long road ahead and anything is possible...if you try.
Why is your life messed up?
Sorry, honey. These things are very important to you. Bullying is an evil of society today and the only thing you can do is ignore the creeps. Believe me, in a few years they will probably be in jail or cleaning public toilets for a living. As for your parents not supporting you, shame on them. But you are obviously healthy and very nice looking-so maybe count your blessings. These years will fly by and you will come out of it stronger.
How is your life messed up exactly?? Put something in the details and then I can share my teenage horrors...or horrors from around the world.
Yes, you can start over as many times as you need to.
