It is enough. No more. Do not think about those people

It is banned. I do not allow to think about them any more. It is absolutely useless thinking. Absolutely.
I can not tolerate if I continue to think about them. It is perfectly useless thinking.
How could I be that stupid?
HOW?'
IS that not enough?
21 years are not enough?
Failures are not enough?
Shit English and the danger of unemployment are not bad enough?
Feeling of failures are not bad enough?
Watch out when I am happy.
