Tired...

I have not been having a very great day.. Started with my mom being a real.. B... My  sister had to have surgery on her ear. My mom has been rude and complaining and arguing non stop all day.. I say anything and I'm "arguing" and suddenly I'm just this HORRIBLE person.. I am so tired... Physically, mentally.. just... Tired.. Done.. It's been constant BS all day.. I just want to curl up in bed and sleep  until I am lucky enough to not wake up... I'm close to my breaking point.. I just don't want to feel like this anymore... I am tired of feeling so depressed, angry, alone, worthless, pathetic, stupid, fucked up, and like a waste of space... I'm just done... v.v Don't want to be alive anymore.. What's the point if not even my mom wants me around and I do nothing but screw up? Maybe I shouldn't be alive..  Everyone would be better off without me... I'm a worthless piece of crap with no future... Why should I live if I don't want to anymore? Only thing keeping me here is that i know it'd cause more problems for my family than it's worth... Suckiest part is I WANT help.. But no one is willing to try and I can't get the help I want and need.. Just done... with everything..
