Yes. You replaced how you look at the situation. Which in turn has proved more than one thing. You were wrong to believe you could not do math, and you were wrong to believe you were stupid. and you were wrong to believe anything associated with this belief. See how much dead wood you have pruned out by going to the root of the problem. See how much new growth there is. If you were wrong to believe this then what else were you wrong to believe. Just by believing you are right, believing in yourself you have flipped a number of core beliefs from negative to positive. Now comes the part about emotions and attitude because you need to bury the negative forever, not put it on the shelf but put it in the garbage. Remember they are all tied together. They are still sitting there, both negative and positive, which one do you want to keep. If you are mad because of all you have lost because of the negativity caused by these people, then you will keep the negative. But if you forgive them and in turn forgive yourself for feeling how you do, then you will keep the positive.
Like our good friend here sunny says "only the present counts the past is in the past and the future is not here." The past is to learn from, the present is to enjoy and the future is where we make sure the past stays there.
Do you see what I meant by it is not the core belief but how you perceive it that is the problem, and what you do with it that dictates whether you keep it or lose it. You can not change the people or what they did but you can change your attitude towards it. You can stop it from controlling your life.
These are really nasty things when they are negative. And if you have a tendency to put thing aside so you don't have to deal with them you will have a hard time finding all the core beliefs.
Your core beliefs tree looks much better with all that dead wood pruned out. On to the next.
By the way did you notice the exposure exercise in doing this, It is all tied together. Opening yourself can be more painful than any physical exposure you do, but you can do it.
Now we add on some more words to the "I can believe," I can forgive, and I can forget. They are going to be just as hard to do.
Here for you.
Davit.
