When all else fails with a moochie friend

I have a friend who is a tightwad and a moocher. She is better off financially than me, yet she begs, borrows and even steals from me. She comes to my house with a 32 oz. cup of water or diet soda ( I do not drink diet sodas) . In the span of one hour she will have helped herself to my iced tea or soda 3-5 times and used the toilet that many times as well. She has bummed toilet paper, paper towels, medicines, cleaning supplies, even mini pads. She takes food from my cupboards, refrigerator and freezer, I notice it gone after she leaves. While she is in the bathroom she helps herself to my expensive lotions and personal products. Last week I put glue in a lotion bottle and she put it on her legs & it broke her out. I hoped it would break her... not.If I go to her house she has coffee, water and flat diet soda to drink.She will drive ten miles to my house to sit in the a/c because she is too cheap to run hers. Yet she has access to a nice pool but has never once invited me to go with her to swim.I could go on and on, she is out of control. I think she needs psychiatric help, my husband says to kick her ass out and tell her never to come back.We have been friends for 40 years. HELP!!!
