People can say whatever they want to help you feel better, but the reality is, YOU have to be the one to help yourself. People will give you support and adivce, but you have to be the one to accept it. There's nothing anyone else can say or do to automatically fix your problems, only you can fix them.

That being said, here's my imput:

First off, I highly doubt your family hates you. Everyone thinks that at some point in their life, usually during their teens....So your family doesn't shower you with kisses and tuck you into bed every night....maybe they scold you a lot and never let you do what you want...this doesn't mean they hate you. Life is stressful, and unfortunately our natural reaction to stress isn't loving kindness....your parents might seem harsh, but it's not because they hate you. At the end of the day, I'm sure they love you even if they hardly ever show it. There wasn't any specifications, so I had to make is assumption.
Also, this might be hard to hear, and I'm not trying to put all the blame on you....however, having been through this with my own parents during my rebel stage...rolling my eyes at my parents and disrespecting them didn't exactly encourage loving reactions from them. I'm not saying you act this way, because I have no idea....but just consider how your actions might encourage or discourage certain reactions from your family.


Secondly, the way you're feeling isn't the only feeling you'll ever feel. This isn't the first time you've felt like this, and it isn't the last, either. If you don't like feeling upset, that means you must care about life enough to care how you feel. Ending it kinda defeats the purpose.

And finally, why are you relying on OTHER people to make your life worthwhile? Of course it's nice to have support and loving friendships, but just because people aren't treating you well right now doesn't mean your life has lost purpose.
