This is an amazing essay. You were able to explore the essence of sympathy and show it through your writing.
However I think the following may be modified this way:
The door does everything in his power to resist that wind and ensure that his owners are safe and sound.
For possible parallel structure add "to" before "ensure"
I feel your pain door, I feel it.
A little bit confusing here, it sound like you are feeling someone's "pain door".
That story was just one example
Probably one of the examples?
That story was just one example of how I can become oddly sentimental towards inanimate objects at times due to the fact that I believe that everything has a soul.
A little long, maybe break it down?
if this is what it looks like.
The "it" here is not clearly defined. Probably substitute it with "essay"
This is just a belief I realize that I have had since I was a child that has allowed me to see life in a very interesting perspective.
Extremely awkward but I don't know how to modify it.
animal for a best friend.
I think "as a best friend" is a better idiomatic expression (I am no gringo so I am not sure)
Sorry its late at night I might revise it more tomorrow morning when I wake up. Please help check my essays too.
Good Luck
