Hi sunshine lilly........not sure if this will help you; it helped me to put my feelings into perspective
Many of us have meltdowns at different stages and in different ways, and it is OK to express how you feel in whatever way is right for you.
Do you have a MacMillan centre attached to your hospital? Mine offers an informal chat, or counselling, plus 4 complimentary holistic treatments which I've found beneficial.
You will come through this; your husband will get his wife back and your daughter her best friend. It takes time, but you will recover :). My treatment was last Feb to Aug, and I won't tell you about the fat, bald hairless alien trying to squidge her radiated breast into her mother of the bride outfit......was hilarious, bit I did it!!!!
Now I have 2cm of hair that I'm very proud of, and as a previous poster said, you can and do move forward....life is different but it is life, your life to live and enjoy.
Virtual hugs and take care......number 6 is the final assault......xo
