Sally,
I am sorry you aren't getting the support you need from those around you. Many people do not know how to support or act with someone who has cancer. I noticed that when my daughter was diagnosed third time w/ovarian cancer.
I have found many support groups in my community who have gone through the same treatments, feelings, loneliness, etc. I encourage you to check with your healthcare provider, American Cancer Society, and/or hospitals. There are many support groups out there.
Remember you need all the energy you can muster to get through this time. Trying to make people give to you what they cannot give makes for a frustrating time for both you and your acquaintances.
You might try praying too. God loves you very much and will direct your path. He promises to do that when we call on Him.
Best wishes,
Pam
