Q, welcome to our community. I am glad you found us too. What a hard time for you and your family.
At the moment, I think you can use all the listeners and help you can get from people who understand sadness, grief and being scared. We're here 24/7. We listen and can offer a virtual shoulder. Sometimes just that can help to get from one moment to the next.
You may find the article Stress and Distress helpful. As well, you may want to check out a thread one of our members, eKIM started Coping With Stress - One Person's Viewpoint.
Do you have a healthcare professional you could talk to about your anxiety as well as your concerns about your brother?
I know you posted late last night – hope you got some rest.
Hope to talk with you again soon.
