I would like to discuss more about 3. I was meditating about it very deeply. My thinking was led by mechanism, that I can talk fully fluently when I am alone or talking to the dog, so my (wrong) assumption was that my brain is perfectly good, it is all about emotions and psychology. But slowly I got to the point, that my thinking was false. I assume, that when I want to communicate, and I want to be understood and listened, some chemicals in brain activates. That process somehow disturb speaking. I think that it is true about that "wrong wiring" and it is just imbalance in chemical distribution, or electrical synapse messaging. It is problem in brain itself and we do not know enough about human to solve it.
