@MicheleR you asked if we can have friends that we can't really talk to about everything. I believe we can, as some people are just at a different stage in their life or have not experienced the same as us. I have a friend that had breast cancer many years ago, and we lost contact when I moved away from that area about 9 years ago, but we have now reconnected. It is amazing now how I can understand what she must have gone through, which was a few years before we had even met. We now catch up every few months, and talk about many things, but when the topic of bc comes up she understands me, and knows what I am going through now as I am still on AI's, she finished hers years ago. We mainly talk about our commonalities, and any shared interests.
I don't bottle up things now, but at the same time I do choose my audience, I just don't think it realistic for people to get where I am coming from , or even any disappointments I may have had with some disappearing when I went through all my chemo and radiotherapy and infusions, now I just don't initiate the contact mostly, those who came back did, and those that didn't I say they were not true friends anyway! I hope that helps you somewhat, and I understand having to find our path again, or find a new path.
Wishing you the best, and take care.
