The only person that is ever going to be annoying on graal is the people that rage at you, now if your not a rager and go round raging people and I can see your not then you won't be bugging anyone, you've just got to think that theres people like you on graal everywhere, maybe you should make a squad and recruit people like you on the forums who are shy and help them to overcome this obstacle in not just graal but possibly life.
This would be a good idea.
Also if you can't talk to anyone but friends you will only have one or two, and also if you think your annoying someone just ignore that thought and carry on chatting.
Good luck.
