请帮忙分析一个句子的语法结构,详细一点更好了,

here 状语置前句子倒装,
真正的主语是a bitterly disilluioned cripple,
其后的a man who held on to his sanity and his wife and his home and his job为cripple 的同谓语
hobbled 为主句谓语,
because of 14 miserable steps leading up to the back door from his garage 为hobbled 的原因状语
所以句子可以改写为:
a bitterly disillusioned cripple hobbled here because of 14 miserable steps leading up to the back door from his garage。He is a man who held on to his sanity and his wife and his home and his job 。
