I am _____ young ______ look after myself.

I am too young to look after myself.
要照顾自己，我还太小。 （抱歉本人完全无语言组织力存在= =）
I am enough young to look after myself.
这句话本身语法就不对，如果改成I am young enough to look after myself，意思就是说 我足够小照顾自己
如果要用enough to的话
young替换成mature或者old就可以了~~

too to太...以至于不能....,否定意思
enough to太....所以可以做到,肯定意思

I am too young to look after myself.我太年轻,以至于不能照顾好自己.
如果换成enough to就是:I am old enough to look after myself.我已经足够大,可以照顾好自己.

enough修饰形容词或者副词通常放在所修饰的词之后，比如这里应该讲：
I am young enough to look after myself.（足够大了，能够照顾自己）
但是这里是前置修饰语，所以只能用too, to。（太小了，不能照顾自己）

句义不符合、你能说你很小足够小能照顾自己么
old enough 还可以

意思不对，
而且用enough要放在young后面

too, to
enough to 结构的语意正好too...to...结构相反。如果用enough to结构的话就得说成I am old enough to look after myself.
