my old friend
Today I'm very sad because I miss my friend,
She was very important for (this is fine, but 'to me' sounds better) me; however, I feel disappointed with her.
I met her two years ago; at first she seemed a stupid girl because she was saying things about me, but they were all lies, just things that people said, so I decided to speak with her and we have been friends for one year and i can meet her really, but seems that she had been lie me about his way of be. (no estoy muy seguro de lo que quieres decir aquí - podrías decirmelo en español?
