mental health

For issues specific to caring for someone with mental ill health.
I find it so hard to atune the care that needed for carers with someone who is looking after someone who has mental health like Bi Polar, I am not saying its harder then something more physical, no way, but very different.
Anyone else feel this way?
As mental health care is different from looking after someone who is physically unwell
I can only best describe caring for bipolar when ill at home in community as the most horrific experience of my life. I have cared for people after accidents and brain damage etc - nothing compares to the unpredicatabilty and fear which being in close contact with someone who is manic - it destroys your ability to share- no one understands how bad this can be- peoplel avoid you - i dont feel any organisation understands how bad this can be -- and when really bad you are suddenly out of the picutre as they get locked up and you cant even see them ......
