I hope I can accept it in myself also, not just understand it and agree with it
The whole point of my post was that these things aren't something you 'hope' for, as if there is some outside entity to yourself, who can grant you permission to accept something in yourself. YOU are the authority. In the same way you don't look at the kitchen and think 'I hope I can produce some beans on toast today, I just need to work on myself first...', you don't 'hope' that self acceptance will come to you. YOU decide to do it, YOU take responsibility for doing it, and then YOU do it.
It's like with an addict, saying they 'hope' they won't use their substance of choice today. It's an abdication of responsibility.
For being very smart I'm extremely confused when I don't understand others' actions
There doesn't need to be any trust of your own judgement, or any hope, for you to make the decision to stay away from people who make you feel confused. It's just something that you do. A single action.
If you understand that there's nothing you need to change about yourself, then all the people who confuse you are just people who confuse you. It's not a puzzle to work out. You don't need to fix anything about yourself. There's nothing to learn. You just feel the confusion, and think 'Nope', and that's it; no more engagement with the confusing person. The problems come when you feel you need to 'work on yourself', because that means you think you're faulty, and therefore are to blame somehow.
You are not to blame for being confused by some people's actions. Not everybody will make sense to you, or to anybody. That's fine. You are responsible, however, for not putting yourself in confusing situations. That's all you need to do: stay away from things and people who confuse you.
