Can Actions Change Your Thoughts And Feelings?

I’ve been a big follower of Eckhart and Byron for years so it’s natural the model is something I love too. Lately I find myself confused though. I love the idea that all feelings are caused by thoughts… but when put into practice I sometime am unable to change my feeling with a new thought. For instance yesterday at a party I had a mimosa and immediately my thoughts became a little unruly and so did my feelings. Is that the action changing the thoughts? Or is the the circumstance?
