Help with personal problem...?

I am a shy person, and I do not interact well socially, there are these people that I have been forced to live with that want me to immediately start taking psychiatric medication. I don't want this to happen, after years of dealing with emotional problems I am finally happy with myself! I may still have social and mental problems, but that's something I can solve by myself or with a counselor! They are thinking of kicking me out if I do not take meds, and believe me it is not my wrongdoing! They don't like me, and I may be annoying, but I'm not bad enough to need meds, please, how can I convince them? I'm not a bad person, just a little sarcastic and annoying....
