大家来找语法错误

把million改为millions of
behaviored改为behaved，behave为动词作谓语，而behavior为名词，不能做谓语
told to myself改为told，told为及物动词不用介词to

没什么语法错误，只是读上去怪怪的而已。

After confessing for a million times, I got confused. I just behaved childishly. I had told myself a million times not to do things like that. You may confess all along.

I got confused， confused去掉d,Told myself million times 加上I， 大概就这样了。
