What should I do??

I should always forget what I should forgotten and remember the things I should remembered...
Happily go through my life without you,
Don't live in the past anymore...
Don't know why the more I want to forget you,you will still appear in my minds..
I really hate it..
Do I still to care about you??
Do I still love you??
Do I hate you or love u??
I also don know what is playing inside my minds..
It's tourturing me everytime, every single minute and all the time...
It'really hurting me...
