Not the internal reaction, but what you do externally -- what you say, what you write -- that's generally in your control.

AIUI, CBT's primary method is to convince you to pause between feeling and acting, so that you can ask yourself if you have made an accurate assessment of reality and can plan an appropriate response.

If you truly have no control over what you think and feel, then you are lucky. You can satisfy yourself with enjoying the ride, free from the burden of being responsible for yourself. If you have so little control that you cannot even take solace in the knowledge that you have no control, then obviously this philosophy will only bring misery to you. In which case, why adhere to it? If you have so little control that you cannot even free yourself from a philosophy that makes you miserable, then try hitting your head with rocks or hard drugs. With enough brain damage, anything can be forgotten. Even unproductive philosophies.
