As hard as it may be I wouldn't disown them just yet. I think there may be a point when you have to do it if it becomes dangerous to your mental well being and believe me I've thought about doing it too...see my story below. How long have you been dealing with this?

I am hurt by my family everyday but I just try to keep plugging along. Unfortunately I don't trust my siblings because especially one of them is very close to my ex and includes him in family events where I'm not invited so my conversations with them are very superficial. I rarely if ever share my hurts, struggles, etc. for fear of the information getting back to my ex and quite frankly they rarely if ever ask anything specific about my life which hurts too. One particular sibling includes my ex and my child in an all family vacation that I'm not invited to and it's so painful. I did do some hurtful things during the two manic attacks I had, but otherwise was a hardworking, supportive pillar in the community and was a friend to my siblings so it's interesting that they wouldn't get that it is the disease and not the person. One of my parents was Bipolar too so we grew up with issues surrounding that but people unfortunately discriminate with this illness. I highly doubt they have educated themselves on the disease and unfortunately probably never will. I too might have to disown my family too but I think you also have to be aware of the future if something bad comes up you might need their support. Who knows if my siblings will be there if something bad comes up for me but I just take my meds, regularly meet with my physchologist and psychiatrist and live a clean life. Hopefully they will see beyond the Bipolar at some point and not in my opinion label me the black sheep of the family. I've been dealing with this stuff for about 4 years.
