Hi Liza,
I'm sorry I'm just finding this post now and I'm sorry to hear the cancer is back. My cancer was treated surgically so I'm afraid I can't help you with what to expect with your treatment. I can help you with the emotional part...which I found to be hardest. First, you joined the best group and you will get the support you need.
I respect your ways of trying to deal with the stress like meditation and prayer and I'm also happy to see you plan to allow yourself time to fall apart, you are human and that will happen. A lot of people here, myself included, took medication to help with the crazy emotions of cancer. I took Lexapro and saw a therapist and I'm happy I did. It is important to stay positive and level headed as much as possible and I feel like the Lexapro helped me do that. Along with my family and my family here of course.
When will your treatment be starting?
We are all here for you and I look forward to supporting to you during this hard time.
