Sorry to hear about your family's struggles. When someone you love and care about are in crisis its really hard to watch and to live through. I just thought id share with you two situations I have encountered with this issue. One is with a good friend of mine. She had mental and drug related issues. They got her into bad situations and very dangerous. I tried to be there for her and protect her but I couldnt. Her actions put my own family and kids in danger and I had to remove myself from her. Her family agreed she needed help. We had the option of Baker Acting her. I dont know what the laws are where you are but they may be an option if her or others lives are in danger. I also had to go through this with my mother. She is bipolar and tends to be suicidal. She has went through several destructive periods and I have babysat her on more than one occasion. I still struggle with her moods and behaviors. She refuses to medicate properly and will not tell the docs how she is really feeling. It is a ongoing battle. As with my friend I have told my mother she has to come to me and stay till she is in a better state of mind or i will Baker Act her. Its hard to confront the ones you love and fear they will refuse to see you. But on the other hand if you dont try to get them help and protect them who will. The only thing I remind myself is safety. Safety of the person in crisis and those around them. Good luck with your situation and I hope your family is able to work through this crisis.
