How do other people get so much control over their lives?

How do they manage to plan something and actually get it done?

How do they force themselves to be capable and productive?

How do they make themselves feel confident that they are doing things right?

How do they avoid doing things that the rest of the world knows are clearly wrong?

How come they can control their emotions so well?

How do they manage to have self-esteem without becoming arrogant or spoiled?

Why are they able to make friends so easily, talk to people without much effort, and pick up on subtle social cues?

How is their judgment so accurate? How can they be so sure that they will never be rotten failures?

How can they be so confident and so understanding about how what they are supposed to do or say or think?

Why are all those things so easy for most of the world, and why can't they be easy for me? Is there something wrong with my brain or am I just a failure?

How I feel is not how most other people feel. Some people do feel as lost as I do, I understand, but if the way I feel about myself was the norm, humans as a species would have withered and died alone in the corners of their caves. So please, don't give me the "everyone feels insecure" answer, because it's not true. Other people have confidence, and I don't, and I just want to know why it's so easy for them and not for me.

I'm sorry I'm so angry. I know it's wrong, but I can't seem to stop feeling angry.
