I think your essay needs to be checked for grammer mistakes. And when you read it, it isn't really smooth. There are some places that
sound awkward. Your story is great, but the essay can be composed better.
That situation was absolutely crushing to my entire being, and being so far from my American family and friends and everything familiar to me didn't make it any easier.
This sentence is a bit awkward and a little long. You might want to change it into something like: "That situation totally crushed me, and being so far from my family, friends, and everything else I was familiar with didn't make it any easier."
I also learned humility, as many times I had to listen so intently to conversations to just follow what was going on.
I don't think this is really logical.
And life swirled on, as another wonderful Spanish family in a different city took me in, and I was able to continue my personal growth in my Spanish life.
Another awkward sentence. Maybe you should write it like this: "And life swirled on, as another wonderful Spanish family in a different city took me in, I was able to continue my challenging life in Spain and develop myself."
The above are only some of the sentences that need improving. I think you should read your essay again carefully and improve it. Try not to write sentences with complex structure if you are not entirely sure you can write them correctly. Good luck!
