Totally Disappointed and let down!

I am very sick and tired of always being let down 24/7. By my own mother. It's making me go back into my deep depression once again. It's been day 2 already and she has said she would do this and that for me and im sick of it. If you make plans with someone aren't  you supposed to honor them and not make them feel let down and alone. i mean what the heck. im so tired of relying on someone totally unreliable. i deserve better and she knows it. everyone is always letting down. everyone knows i deserve to be happy and i can not make myself happy by my damn self. i feel like throwing my laptop right through the freaken window. i dont feel loved and i know for a fact she doesnt love me. no one does. and im so tired of it. ppl are always always always saying oh i love you but hell no they dont mean it. dont make promises that you cant fufill. otherwise youll end up with with an angry hurt person like me. guess im not feeling good after all.
