You didn't screw up. You only expressed fears and hesitation. I would find another t (as many have suggested). I'm assuming you sought therapy yourself, voluntarily. That says to me that you are at least willing to look at the negative patterns and see how they impact your life. Your t is missing the boat on so much with this. It's normal to start therapy them question if it's worth trying, especially if there's depression and/or anxiety in the mix...
try to be gentle with yourself, and perhaps find a new t that is willing and able to help with bumps in the therapy process.
