You need a support group of people with better understanding of what you are going through. As another woman whose cancer is not breast cancer, I felt isolated in those women's groups - not part of the "pink sisterhood." Heck, in a social/sports club I'm a member of, where there are a good number of cancer survivors, I find I fit in with the men survivors - they've had colorectal cancers, and similar treatments. (Mine is appendix cancer.) I'm not part of the "cancer sisterhood" there either.
Do you have a Gilda's Club near you? They have general support groups with people with different cancers.
Also, use support forums like this to find more like-minded people.
