feeling so cheated and useless...

i realli don get it... why does everything seem to go against me? when i put in the effort to do something and i always don get the results that i deserve... when i have studied so much harder for my promos but it seems that i am going to have at least 3 R papers... i seriously wonder why... this is so unfair... if i did not study and i screw up my exams, i noe that i deserve it but now i can tell myself that i have put in my best effort and i don feel regretful at all. Is this realli the best i can do ? Am i that useless? Do i realli don belong to the sch i am in right now? Izzit too competitive for me? now i realli don noe, i have been thinking of it since the end of my promos and the picture will be much more clearer when my results are out... R papers here i come
