这句英文有错误吗？口语这样说是不是不好？感觉像在说中文

没错误。确实有些chinglish。

用形容词，即make sb confident engough to,好一点。

补充，有错误，呵呵，这个to后面接原型

它让我有足够的自信去面对困难的问题．
非常口语，带脏字
it makes me have enough balls to face shity problems.
不带脏字．
it makes me bit bullet to deal with troubles.
口语要求表达快速流利清晰．不要用长词

应该改成
It makes me confident enough to face difficult problems.

It gives me confidence in facing difficulties.

It gave me enough confidence to face difficult problems.
我认为这句更口语化些
