I never strived for "Positive Attitude" during my treatment - just an active mind and body that kept me from going down a dark rabbit hole that is hard to get out of. Fortunately I worked throughout my treatment so at least from 8 to 5 I had something else to occupy my mind. I did a lot of fun reading and knitting - things to keep my mind engaged. At night when trying to get to sleep when my mind was idle - I practiced counting slow breathing so again my mind was occupied. There were times when I fell into the rabbit hole and sometimes I was able to get out easily other times it took a while. Even now over 1 year passed all treatment, I sometimes focus or wonder about every new ache. I have a small note pad and make note of them so I can bring them to my oncologist the next time I see her. I'm TNBC BRCA2+ and what I've read is I have a higher recurrence during the first 5 years. Maybe once I pass the 5 years I can start to relax more - only time will tell. I hope you find something that works for you even if it's to vent about your worries to people who understand what you're going through. There have been many posts that I've made here that were emotional "vents" to others that understood my journey.
