I agree with all the others who have commented and said that you are most definitely NOT a baby....BUT, if you feel like acting like a baby right now, then I say go right ahead. It's perfectly understandable and, for those of us who never really had the luxury of acting like babies and children when we really WERE babies and children, sometimes, we just need to give ourselves permission to feel that fear, insecurity and vulnerability now....regardless of current age.
Wishing you peace and courage as tomorrow comes.......
