Am i tat bad in lying?

This story started a long time ago...when i was still young. I did learn to lie, ok....but i never suceed in it.
I lied to my primary school teacher, but once they asked "Izit??" I'll juz burst into tears and tell the truth. Em...nevermind...i'm still a kid tat time.
I lied to my secondary school teacher, but when they asked "Are u sure??" I'll juz start to stutter and there goes another failing experience.
But i did trained myself to lie to my classmates. And again i failed....Coz everytime i'll feel pity and sorry for them, and evetually, i am the one who went and said "Hey, sorry man...i lied to you."
OMG!!! What am i doing?? Where on earth can u find such a NOT CLEVER ppl hanging around in M'sia! Obviously i never think that this is a disadvantage for me...as i'm so not use to it. But today, when Jolyn asked me about somethg and i told her the truth, i did, i swear...She juz popped out this word "Eh, dun lie k, u'r not good at it!"
OMG!!! What is tat??!!! For a friend tat i juz knew for about 1 month and she knows i can't lie.... Am i tat suck?? Oh my...
I know its not good to lie...coz i do believe in what my pastor and parents told me. But the fact is, If you duno how to lie, how are you going to survive in this earth? Gosh...do teach me to lie!
