You do sound stressed Elizabeth. I even started to feel a bit stressed as I was reading your words.
I am not sure if anything I said would help. But I can tell you some things that work for me when I feel stressed.
I just cry, let all the emotions go.
I will write a list of everything going around in my head.
I will attempt to focus on one thing at a time on my list. Start with the most important or pressing thing first.
I will pray
I need to say no to some people or no to some things in my life
I will meditate on God's word. "Let not my heart be troubled, and Lord I trust in You"
I go for a walk
Watch a good feel movie
Try to eat lots of veggies. No sugar
Go for a drive in the country where its nice and quite
Go to the pet shop and look and look at the coloured fish swimming around
Some times I have waited too long to do all or any of the above. And then everything turns into one muddled up snowball. My thoughts get mixed up, cannot think clearly, I see issues larger then what they really are, I am not a pleasant person to be around, I would feel weighed down (think... giant snowball racing down a hill and wiping me out or sitting on top of me)
And I am not sure how much you tell your hubby or other family members what you are feeling. But I wonder if you should say more.
