I am so sorry your family is insensitive. Maybe what you need is a good support group. Maybe ask your doc the next time you have an appointment. You may have to learn to self soothe many people do not have the support. Do you live in a large center or small town. Maybe try and get out such as swimming something that is not hard on your body. Do you have friends? I agree your brother is just covering up something. Do not take the same rhoute he has this will surely end in bigger problems.
Take care, Amy ( I care)
