i really need your advise

hi there,

today..im very sad..
for your information, i've graduated from local university with 3.03 cgpa..i did bachelor in business administration about 4 months ago.. i've sent many application letter but i received very little feedback. i went for some interview but i fail to get the job. now, i feel very bad.. and i'm sick of looking for a better job. maybe im not good enough.. but why dont they give me a try? they won't regret.. but what can i say?

actually, i dont really like study in BBA Finance, but i have to study..because my brother wanted me to further in that field. i love IT, computers, technologies, graphics, animations.. but i never have chance to study my interests..

you see, studying for 5 years to get degree, i've wasted so much money...my mum's money.. we are not from the rich family.. now, my mum is sick..so sick..and i'm afraid she's going to die.. and i dont have good work with good salary to buy her medication bills. now, i am working as a clerk..with RM 200 salary.. and every nite i work as a part time teacher working 16 hours per week...with payment RM 200. so, my total salary was only RM 400. How can i afford to pay for her medications, for anythings that she needs..etc. God help me..i feel terrible.:(
