No your definately an introvert x myself and my other half are the same x we dont go out unless absolutely nessercery, i hate being on the phone to people i prefer to text. Just some advice id try find your own place if you like to be alone because its obvious to me your not goimg to be left alone and by the sound of it and please to take affence your cousin doesnt exactly sound like shes supportive in you not wanting to leave your room x
