My girlfriend said she would come to see me and laugh at me.

It's very generous of your girlfriend to come to see you instead of asking you to see her. On the contrary, she thinks you don't like her appearance very much. Otherwise, you should be glad that she came to see you. However, you don't feel this at all in your writing. You invited a girl to visit you so far away, but you don't like her very much. Aren't you ashamed to do so? If you like her, call her. If you don't like her, don't do something that both parties regret.
