You have said you want to kill yourself. That's very extreme. Do you really mean that, or you are saying it for effect?
If you really mean it, there is something going on not just with your hair, but with your mind and you should seek professional help.
On the other hand, if you are just saying you want to kill yourself for effect - as an exaggeration of how you really feel, and/or to simply draw people to this thread, that's not cool at all.
