I went through a lot of the same.
Hang in there it gets better on the other side of this hill.
I had ice cold feet and sweaty body. Soak the sheets sweat.
Sleep will come. You will be surprised how well rested you'll be when it does.
I swear I never really slept well until I quit drinking.
More like passing out than real rest.
Keep up the good work, And keep us close.
