She is medicated, but still struggles. I am having trouble finding the tolerance of this mental illness I need to help her through these anxiety attacks. She is pretty much always anxious, but when she faces a change or a family member is having a problem, she loses any coping methods she may have. I need help for my sanity and to deal with her lovingly.
Drugs are good. It can be difficult to find the right one or combination of ones. After several experiences with amateurs, I would never, ever allow anyone but a psychiatrist to prescribe such drugs for me. Internists and GPs are often willing to write scripts. See a specialist!
Training is good. Knowing how to recognize the anxiety and learning some techniques to deal with it when it arises is very important. I'm not sure that all elders, especially those with dementia, could master this, but if it is possible, it is great.
Having other people who are sympathetic and understanding but who don't buy into the doomsday scenario is also very useful. Caregivers can often be that person.
Having meaningful things to do, avoiding boredom, focusing on the positive are all helpful and useful. But if you have a chemical imbalance that predisposes you to anxiety, that may not be enough. I know.
If you can keep them entertained, not bored, and busy with something positive, it sure helps them stay peaceful and content as possible.
So is it helpful to think along these lines? Is it possible to add something really positive to her daily routine, to immunize her against future anxiety episodes? I remember that it also really helped us before to read Robert Sapolsky's Why Zebras Don't Get Ulcers, in which he explains how chemically our resistance to stress can be destroyed as we age. Good luck!
You may recieve good advice here but you will get better and quicker results if you do not go by the trial and error method. What works out side the medications area are certainly worthwhile suggestions.
As to family problems, try to shield her from that to AVOID her anxiety. If you can't? Try something like, "Oh, mom, we're just gossiping. Everything's going to be fine!"
I'd also suggest you speak with your doctor to see if her meds need increasing, It's not an exact science. Lots of trial and error goes on.
