I am happy that things are getting better. It is easy to feel overwhelmed when you have things going on that are out of your control. The stress is huge and the normal screaming that my U2 does that I have lived with for years, seems to be magnified by 100.. I find what helps me is taking a few minutes for myself. I get up earlier in the morning to have coffee, check emails, etc. I find that when I am really stressed doing something like this really grounds me. My bird is still covered in the morning, so she knows to be quiet. If she is awake, I give her some of my breakfast and put the cover back. She happily eats and mumbles.
It is amazing what a few minutes for yourself can do when you are running around the rest of the day. It helps me a lot.
I think you have made great progress. Keep up the good work!
