跪求英语语法上的问题解答!!!

I've come to the conclusion that (I find a reason not to be happy with （where I am at that moment.) )
第一个括号（外层括号）里是that引导的同位语从句说明conclusion；第二个括号由where 引导的同位语从句构成句型not to be happy with sth中的sth成分。整句话这样理解：我得到的结论就是：我为那个情景的不开心找了个理由。

1 not to be happy 做reason的定语。

2 I've come to the conclusion (主句)that （同位语连接词）all too often I find a reason not to be happy with where I am at that moment.（同位语从句）

3 the conclusion that + 句子 ---------是同位语从句

你好,不是不定式,
实际上是.i find a reason (why i am) not to be happy with where i am at that moment.

我得出了结论,那就是,我往往找到 我对彼时处境不高兴的理由.
