Hi DP.  Welcome to the forum that no-one ever wants to join.  I am a carer for my husband, who has several very serious and life threatening health issues.  I myself have stage 4 cancer, but fortunately, at the moment, I am still able to do things and have not yet reached the stage where I have become incapacitiated by my illness.  I really feel for you.  Having 3 children to take care of and a husband in hospital having chemo is a lot on your shoulders.  You have every right to be feeling lost and tearful.  However, sometimes it is a huge relief to simply let everything out and to tell others what you are going through.  This forum is a very  nice community of folks DP, and everyone on here has either got cancer, had cancer or is taking care of someone with cancer, so at least you know that you are connecting with people who know exactly what you are going through and how you are feeling.  I wish you, your husband and your 3 children the best of luck, and somehow you will get through this.........the inner strength just seems to come from somewhere.  Take care mate, Violet, x
