It is horrible to feel powerless yismymindblank,as you must do over a situation such as this.If it was me I'd keep what control I do have by resolving to make the most of what I have now and can do now and I would hope I could keep as happy and as involved in life as possible until the end.It is hard I know but the choice is either that or be miserable now and throughout the worst of what will be.It is tough I know I hope you find support through this and people to love you too!
