Very true Judy.
I know how exhausting it can get, you two just need to regain some neutral ground back spending time with each other remembering why you love each other in the first place without all the crap of life interfering once in a while.
Just work towards tomorrow
forget about today. It's ticking by while you sit and dwell on it. You're blessed in so many ways, you've got so much to be thankful for.
I would kill to already be married, getting to know my first born! Others admire your youth, beauty and strength. Your husband is a hard worker... (I don't know you well enough to continue this list, but as you can see it is a great start!)
I recommend the movie "The Story of Us"
Take it easy. Not everything is always going to be perfect, you are going to wear yourself down if you set such high expectations of yourself and those around you. Take a moment to smell the flowers, busy your mind with something you enjoy when you find yourself thinking dark.
