It is a hard disorder to deal with not only for the people in your position but also for the people who have it. If your family members are not on medication I would suggest that first. Otherwise I would suggest talking to your mother about how you feel and if you feel your family would agree to it I think it would help to get family counseling. This site may help you understand it a little better. http://psychcentral.com/disorders/sx1.ht... They also have a link to other resources and you can always contact a psychologist and they usually are more than happy to answer any questions you may have.
