Glad to hear that your daughter's chemo is helping. It would be really disappointing to go through such disruptive treatment and see no changes. Yes, side effects can be so debilitating. It might help if she has a support group. There are some that operate on line. In person there's the Cancer Support Community which I love. They also have support groups for support people, whether they be family or friends.
Family has to come first even though you've had to give up activities and friends you enjoy so much. It's probably not the way you wanted to spend your retirement either. Maybe it's time to get some paid help so you can sleep better.
Life goes on here. After the high heat we're having unusually cool weather for this time of year. Cloudy and in the 60s. Not cool enough for the heat to come on at night. They tell us it will warm up.
The governor here has ordered us to wear masks starting Monday. Delta version has really taken hold here. Non emergency surgeries have been cancelled because the hospitals are filling up. Wouldn't want to be in a hospital full of COVID delta people anyway. I don't mind wearing a mask again but had started going back to the gym. I'll stop again if a mask is required, I'm a heavy sweater and will have to bring extra masks with me for a change.
The online public library has been my friend through all of this. Books are available anytime.
