I'm so sorry that you are feeling this way. Many women have found that getting some counseling, talking with a psychologist or even just having phone counseling (Cancer Council have a helpline) can really help. There is a process of grief with losing a breast and it can take a while for this to really hit home because we are so busy just dealing with the cancer issue at first.
The one and only time that I felt a bit this way my husband asked me did I feel differently about him because of his scars(he has had 3 skin cancers removed from his face which have left visible scars). Of course I actually feel even more loving towards him because of his scars and it does not make him less attractive to me at all. I then felt reassured that he was feeling the same way about my scars.
There are many ways to help ourselves feel better about our self image. I have found exercise has really helped me. But also I have found a lot of strength within myself that I never knew I had because of having BC. I think that strength has helped me to feel ok and confident about my scars and how my body looks now.
We all have moments where we feel down but if you are feeling overwhelmed then giving the Cancer Council a call might be a good idea. You don't have to feel alone with these feelings and sometimes we all need a bit of help to cope with the effects of all this. Hope you can get some help and feel better soon. Take care. Deanne xxx
