Could you correct my writing, please?

Could you correct my writing for grammar and vocabulary? Thank you so much!

There was a man who wandered around the desert. The only one who walked with the man was his shadow. One day, he couldn't stand his loneliness so he gave the shadow one of his arms. The man kept walking. The sight of the desert was the same everyday and the rough sand in the wind made him get more worn out. He was so tough inside that he took his another arm off and gave it to the shadow. The shadow with two arms looked quite like a person. He kept walking to cross the desert. He was lonely and hard and the only thing he could see is the yellow sand of the desert. Now the desert, which he walked on, but is never ending, seemed like the whole world the man live in. Then he gave the shadow even one eye of his. He took off parts of his body and gave them to the shadow whenever he felt lonely and hard walking on the deserted world. Now the shadow could walk with a feature of a perfect human, but the man even didn't have a shadow any more.

(I would like you to give an alternative word for 'wander around' in the first sentence. 'Wander' means just 'walk around slowly' in the dictionary, but I would like it to sound stronger. For example, the man got lost in the desert and felt locked in the desert. He was totally exhausted of this situaton and desired to escape. He was busy keeping walk around and around, but he never could run away from this desert. Thank you!)
