Hi there ~
Living with bipolar disorder
is not easy. It is easier do live with bipolar on medications and on therapy with counselors. I am glad that you did the right thing by calling the helpline. It is useful to let someone know so that they can rescue you. Please also use other community resources if you do not have medical insurance yourself. I wish you all the very best. You can lead a life that is similar to any other. There is no doubt about that. As for your brother he needs some psychoeducation
and he will come to terms with your disorder. I am sorry a bad fight came about between you both. However he will realize down the road.
I hope this helps. See a psychiatrist
as soon as you can. Take care and have a nice day !
