KT,
It's not easy dealing with another's illness, as I experienced this weekend. A visiting friend stunned me as she talked incessantly, without opportunity for me to respond, making it a long day. I still feel the effects of the day, and am glad she left.
What do I do, since she lives in another country? I can ignore her, but unlike yourself, we have the dilemma of responsibility. I know she has medical professionals in her family, so I imagine they're aware of this behaviour.
I also feel like a hypocrite, since I've been wound up too, or "negative", and a host of other things, so how can I judge another? How can I marginalize others, when I feel that?
Fortunately our forum lists guidelines for compassion on this website toolbox("how to help fellow members), but we can turn the site on and off. In your situation, you sound like you live with a family member, and are considering some action to help them. I'm sure the health educator will give us some direction here. Maybe the educator can also clarify this website's policy regarding posting other websites, since I think it's ok for Davit to mention something which is not commercially profitable, as is the case I'm sure.
I would definitely be speaking with your counsellor regularly about family dynamics, KT. It's where our style of relating to the world begins.
