Self-defining memory

The following is my actual assignment that I handed in for my personality psychology class, and I would like to share with you all.

"I remember when I entered college when I was 20 (that was 5 years ago), it was my first time leaving my family and studying abroad. I felt like an alien when I first came to Vancouver, because I did not know anybody here, and I did not understand what the teachers said in class at all. I was so homesick and I also had symptoms of depression, in which I had no appetite and I sobbed myself to sleep at night. That was the saddest and lowest period in my life, and I thought I would not "survive". Now when I look back to this memory, I notice that I am a slow-to-warm-up person, and I need time to adjust and adapt to a new environment. Moreover, I realize that time does fly no matter what situation you are in, happy or sad, thus, I need to learn the lesson of patience of perseverance. This memory helps me to understand that if I want to grow up and mature, I must be willing to take risks in life. I thank God that He helped me to get through this depressing period of my life, I learned to fully rely and trust in Him, and I have a closer relationship with Him ever since!"

So what is a self-defining memory?
By recalling a particular memory, it helps people define who they are, and reveal something about how you feel about yourself. It may be any memory, happy or sad, but should be one that you have thought about many times...

Do you have any self-defining memory to share?
