sudden thinking ... fear

I always think that I am capable of doing something such as getting good grades in my study ... seriously it is not easy ... I tried my best to study but it just cant get into my brain's memory ... when your family's hope all on you alone seriously it is a big and heavy burden ... Sometimes you will feel like giving up and rest ... I hate it when I was look down just because I get low marks on my exam unlike them who is genius or smart people who get good grade for their exams ... why on earth must we always compare the marks or grade ?? just because it is our human nature ?? It hurts when your college mate look down on you and look at you like you are the dummy and they think they know everything ... I hate those who discriminate people who are not that smart or slow learning people ... They don't have the right to discriminate people ... stop comparing please ?? I am so tired having to live within people who wear mask on their face all the time ... people who are nice and kind in front of you and back-stab you behind is the people you need to avoid ... I am surprise that some of them even smile towards you and talk to you like nothing happen and when you turn around they start to count all your bad habits or something that you didn't do but was accused of ... what I can say is be alert always =(
