Will quote from Fifth Element.."What doesn't kill you makes you stronger"...I laugh every time he says that..I really believe it..There are only a small percentage of people in this world that find life a bowl of cherries...Most of us only get to deal with the pits....
You should be very proud of yourself...Not only have you made a good life for your kids..But you are a survivor.....And now you are looking after you...that will make you even stronger....
