This conflict between SHOULD and DONTWANNA sets off a trigger in our heads as we end up in this ping pong spiral thing.
For example: I should, but I don’t want to, so it must mean that I’m terrible (lazy, stupid, rebellious, whatever we got labelled when our perspective was considered just an excuse not to do what we were supposed to do).
Or: I know I probably should do this, but my body and brain keep telling me that I don’t want to do this, maybe I should suck it up, why can’t I suck it up, I must be weak, oh, I’m weak, that’s it, I can’t because I just am not good enough, ah, that all makes sense now, I’m just not good enough. Whew. I got my answer. The answer is that I am just not good enough to get this right.
