Stuck in the loft forever :D. I used to do a lot of catastrophizing too. What if this goes wrong? What if that doesn't work out? CBT is great for that... forcing you to go further than the first anxious thought: well what if it does, then what? And you explore that possible outcome. And the next. It's great that you're solving problems and shaking off unwanted thoughts.
I would've just waited for one of the lads to do it :D
I'll have to wait for my girls to get a little bit older, although Hazel (my 6-year-old) is itching to get up the ladder.
