Getting poor grades is like letting down my family !

Was quite surprised ! My Sis SMSed mi saying mum call mi n Josh to go her place for dinner!she will be treating us pizza! Was asking myself treat for what event? Then asked my sister what is it about ! She said that my mum said I work to hard for sch and wants to teat mi something ! Felt a bit touched but felt sad again as feeling my hard work ib uni never been paid off ! N my results really is a disappoitment so I feel more sad n depressed after that ! ! Btw u also can't make it ! Study first ! No time for dinner also ! No mood also ! It's like there's something to celebrate for my polystyrene result but not with my uni result ! Pls ! Really feel so useless ! Hope tml will n a better day !
