I do not cycle as rapidly as you describe.
However, the rest of your post fits me to a tee. I have spent years trying to figure what I truly believe and think about multiple things. Who/what is the 'real' me?
The ONLY constant in my life is my intense, unconditional love for my children and grandchildren. Everything else is wishy-washy, flip-floppy....that natural hypocrisy you describe.
You are not alone. And, while I haven't always thrived.....I continue to survive....and when the rubber meets the road, I can even sometimes take a stand and stand there.
