可不可以帮我对这个英文句子进行一下语法分析?

I was born in a family of declined fortune has to fend for myself.
我出生时，家道中落，不得不自食其力/自力更生/自谋生路。
这句话好像有语病的，把两个句子合在一起说的。
I ，born in a family of declined fortune ，have to fend for myself.
更地道的说法是：
Born in family of declined fortune,I have to fend for myself.
主句：I have to fend for myself.
从句：born in family of declined fortune
