The hard part is over.
I'm matching you with one of our specialists who will be calling you in the next few minutes.
If you haven't talked with a doctor about medication, you probably should, as some people can be helped. However, don't expect this to just disappear. It will be worse some days than others, and in your case it seems to be worse at night, which may be part of sundowning.
I'd suggest a doctor visit to see if anything can help with the anxiety.
