The Good News and The Bad News

Ok, good news first...I feel all better! I'm completely back to my "normal" self :) We're still going to recheck my thyroid and make sure it's not being a little troublemaker, but all else is well...with me.
The bad news...mom has a sinus infection yet again and the antibiotic makes her feel really goofy. The worst part is that this is about her billionth sinus infection and some of them are getting to the point of being resistant to some antibiotics, but she's really sensitive to meds like I am and doesn't have a whole ton of options with them.
And the really bad news...Grandma Hill's cancer is back. Here's the odd part, it's not the breast cancer she had last time, but some type of secondary cancer that has spread all down her side. She meets up with her oncologist again on July 29th to set up another plan of treatment and get some more details. I'm pushing her to get a second opinion just to make sure that an unbiased professional agrees with her diagnosis and plan of treatment. On the other hand, Grandma Baileys has developed a nasty habit of leaving her house on her own. She doesn't drive and has now twice wandered out of her house. The first time, she barely made it down her street. Now, she doesn't live in the best of neighborhoods so it's definitely dangerous, but thank goodness my aunt was coincidentally driving down the street to Grandma's and saw her. She picked her up and took her home. The second time she left (just a few days later that week), Grandma made it down a very busy street and to a shopping center. Now for the REALLY scary part, she got into a car with a stranger. Seriously, thank goodness that woman took her to the police station and they called my dad and aunt. My Grandma was actually really ticked and thought it was all their fault. We're trying to decide what to do because it's obviously dangerous for her to be home alone, but she doesn't want to live in any type of assisted living facility and can't live with any of her own children. What to do? Any suggestions are welcome...
Please keep us all in your prayers and have a great weekend!
