英语句子,有语法错误吗?

brave 作动词后面要加 oneself
You must do something for you,后面的you要换成yourself
In order to.不能自己成句,前面或后面要加半句,所以建议把前面的叹号改逗号,惊叹号挪到后面.
If you now think that you should do something to fight back,please immediately brave yourself to do it!No matter what it is!Do not regret it!You must do something for yourself,for your dignity,in order to prove that you are no longer a wimp!
这样虽然句子还是有些生硬,不过语法就没错误了.要改的在顺畅些,这样改：
If you now feel that you should do something to fight back,brave yourself to do it immediately,no matter what it is!And do not regret it afterwards!You must do something for yourself,for your dignity,to prove that you are not a wimp anymore!
