Hi Stephen
My heart goes out to you,mainly selfish because I know one day I am going to be in the same position as you,I hope that does not seem unkind,why has it taken you so long to find this site,people on hear understand exactly what you are going through,some have already been there,and others are preparing themselves,but hoping there is a cure around the corner.
Your wife lives on through your children,and that is what is important,grieve for Dawn,but try to hang on to the good times,your future lies with your children,her mum has lost a daughter she cannot replace.
Do not worry about the grammar,its the feelings that come out of your message that,s most important.
I hope we can be there for you.Eve
