Hi Jay Christy,
Welcome to the forum. I can relate to what you are feeling. It started the same way for me, at fifty.
And I still feel this often, but with less intensity. I guess menopause aggravated the anxiety and depression, which I was prone to.
The days that I dont work and have nothing planned do bring those feelings up.
Anxiety with depressive symptoms got too much last year, so my doctor put me on antidepressants 6 months ago.
What you are describing seems to me like anxiety, talk to your doctor about it, maybe adding a medication would help.
Keep posting, others will chime in eventually.
