Oh Gwen - thank God they are both alive. Its so sad to hear of these things with such young kids but lets all hope that they learned something and there wont be a repeat.
PLEASE take case of yourself right now - you're already under so much stress that is physically affecting you and if you take on too much you may have a repeat attack. please know when you have done all that you can and get help from others when you need to. Remember that if you land yourself in the hospital you'll be of no help to anyone.
