I have trouble with some affirmations as well. If my brain holds data to the contrary, I cannot use it because I instinctively fight it. For me, it helps to change the statement to something that is true.

Both of the examples you gave would be difficult for me, but I could adjust them. 'I know how it feels when safe and I know how to find it again after periods of distress.' And 'Although it feels like I have taken many steps backward in my life, I know I am supported and I am moving forward in general'.

Or something else completely. I like that you're working the system, but sometimes it makes sense to learn the concept and apply it best for you. That gets you closer to that highest good you're aiming for

Now this can be a little tricky because sometimes we make adjustments that accommodate features of ourselves we really do need to challenge and change. In those cases you have to look at the results of your adjustments honestly and judge whether or not they add value. If not, return to the basics or design something entirely new.

If you struggle to judge yourself objectively, a friend can usually help. You'll figure it out.
