Do I control my thoughts, or do my thoughts control me?

Do I control my thoughts, or do my thoughts control me?
Who is I, my, or me?
I’m thinking life is what lets us think, and our thoughts are formed from the inputs to this body we are in.
Maybe that’s why someone once said “don’t always believe what you think”.
Do I control my thoughts, or do my thoughts control me?

I’m thinking that feelings might sometimes be a result of our thoughts, and also can cause us to think.
So feelings might sometimes be controlled by controlling our thoughts. But other times the feelings may come from I, my, or me, which I’m calling life/spirit/living/universe, whatever. Or maybe not.
