'I am a delegate for Model United Nations at my school' - United Nations Model

Could someone read this and give input / edit ?

I am a delegate for Model United Nations at my school. I can not say I enjoyed every minute of my membership, but I can say it has taught me a lot. Being a member for four years has taught me how important world issues really are.

Every session, I have represented a different country other than my home countries such as the United States and Korea.
At the most recent session, I represented the country of Iran on the topic of, "Iran's Nuclear Program." I had an instant feel of trepidation. I wasn't the best delegate out there, and certainly not the best speaker. To no surprise, the session went unresolved. Although the M.U.N delegates did not come up with a resolution that all the countries could agree on, I believe I tried my best to follow what the real representatives of Iran might have done.

MUN has taught me it's not easy being a country most people have a prejudice notion on; it has opened my eyes to the bigger world out there with the issues people are trying to resolve.

This is a really interesting topic and you did well elaborating on it. But there are some errors in grammar, and it seems rushed, like you got to the conclusion too quickly. I'd add more detail about the Iran discussion both positive and negative, and give a reason or two why it failed to get a resolution. That might help.

AH yeah i know i rushed to the conclusion cuz i have a 150 word limit
and thats actually at 180 right now :/
