Why is the world bullying me?

Example 1: A malay from class 2I 2011 Victoria School keeps jeering at me and keeps calling me names.
Example 2: When I was in primary school (Nan Chiau Primary School), I got bullied by a particular bully called Sum Jun Wei for 5 consecutive YEARS(2004-2009), despite my size.
Example 3: A private in BlackShot keeps killing me... why do they have skill and I don't?

I could go on for ever and ever, but that would be a waste of time, really. Can someone help me? Please leave a comment.
