I'm very much like you on Graal and in real life. I am very introverted so I know it can be hard to socialize. However just PM someone, anyone. If they reply nicely then that person would be a good candidate to be your friend. If they are rude etc, then they aren't right/don't deserve to be your friend. There are thousands of people on Graal, don't get hung up thinking you are annoying one or two people. Also if they don't want to receive pms they should turn them off, so it's not your fault that you pmed them.
