Dear Ana, I am sorry to hear about your Mom. Our deepest condolences to you and the family.
Your Mom lived a full life and then smoothly made her transit to the other side. Her blessings and care will always be with you. The love and affection you had towards her made her pass smoothly to the other side.
The people who are toughest in our lives are the most dear ones at soul level and with their tough behaviour they help us alleviate, like your daughter rightly said if she would have been any different you would not had been the person you are today.
You will always have her fond memories which will bring a smile to your face whenever you think of her.
Love and Hugs to you my friend. Take care
