The past a guiding light ot the future?

I know i did not want to bring up the past again but sadly i realised its hard to forget the past. Without the incident that happened last year, i would not be so caught in 2 minds right now. I could not really bring myself to put in 100% in my effort to persuade because what happened in the past still lingered on in my mind. It was supposed to be a simple procedure, just as it would be now but i dunno. I really fear that there are hidden unknowns behind every corners. I know i m holding back a lot just now. Maybe its because i m afraid to take up responsibility again. I know i m not alone in this as i can see from the look on my parents' eye but i m really afraid. I know that that should be the ideal course from what i've read and understand. But yet I have no idea whether i will be able to withstand a second blow if something were to happen again (touch wood). Haiz...
