Hello, Wanttohelp, and Welcome to SR!!!!
Lots of wisdom here from people who completely understand. I hope you will take some time a read around the boards, especially the "stickies" at the top of each forum.
I guess my short answer to the title of your thread is NO. You cannot make someone realize they have a problem. You CAN learn to detach from the craziness and take care of yourself.
Hugs and prayers, HG
