It isn't unusual to miss the presence of those in ourselves Nikki. You, as a caretaker (of wonder...*grin) to so many family members, just naturally put yourself last..out of habit and necessity I think.
The problem is our bodies know better and start "talking" to us...we become ill and we ourselves need caring for.
Instead of shutting down when overwhelmed we need to remember that the shortest prayer is "HELP".....and it's there for the asking.
Very recently I needed help with a graphic visual I could not get out of my head...I was incapable of helping this person because of the horror of something her husband had said to her, and she repeated to me. I told the one person in the world that I dared to..my Pastor and in three short sentences, she lifted it from me. I was amazed.
The lesson for all of us is...when we need help...
go for it!
