I still have my husband but have been caring for him for 15 years. What you are going through is every carers nightmare.WHAT DO I DO?? They say time is a great healer and i do believe that, but i can imagine it being hard at the moment. Your husband is still with you through your children. I am a strong believer that they are with you in spirit. Talk to him when you feel lonely. He would not like you to be unhappy it is hard but things will get better i am sure. You have been strong for your husband and you will be strong for your children. As they grow you can feel proud as your husband would in what you have achieved.
My thoughts and prayers are with you.
KEEP STRONG XX
