Depression

It'll get better, just keep believing that. If you end your own life early, you won't know when that 'Happily Ever After' comes. It could take a lifetime to get there, but if you commit suicide, you'll never know the great things waiting for you. Stay strong and keep waiting. It will get better

I know how you feel, I actually suffer from a small amount of depression as well and... well I'll message you the rest.
