dilemma...

Some people say that certain thing can not be regret of... I agree with it but sometimes, the thing that we had to let it go keep on striking our mind... Everyday, every moment, every second...

At this particular time, I'm facing the situation and I kind of don't like it very much... It somewhat had affect my works, my concentration on other things as well as my daily normal life...

What should I do? Should I consult someone good at this thing? Should I ask my seniors on what their opinion is? Or should I just let it go like that?

The main thing now I can not bear with all the pain of thinking the same thing again and again... I wish I can solve this thing as quickly as I can...

Can anyone help me?
