Hatred:
Attacks suddenly. Hatred to immigration officers. Hatred to the Thai. Hatred to Russia that is still in the stone age. Hatred to everything around you because the Thai push you back to the stone age.
And the most important, is this hatred to the Thai desire to save face. The Thai invent all kind of things not to admit their mistakes. There is even such expression "Don't thai to me!" Means don't be a Thai and don't try to wriggle out with more lies. And even ok with lies, for example an immigration officer will ask for a bribe and you will have to give it, because even if your documents are in order and you point it out, the officer will do everything to revenge you because you put his face to his own mistake. This is the key element feeding your hatred.
This stage is short. Hatred is like flash. That puts a full stop in this stage of your life. Thailand will never be the same.
Surely Thailand is worth goint to, to spend a winter for example, but moving...
Moving is not possible.
It is not possible to move to Thailand, it is not possible to make it your home, it is not possible to stay there forever, except dying there. And the matter is not in visas, it can be solved, the matter is in personal growth, there comes the time when you understand that you have overgrown Thailand and you understand that you cannot live there any more. Spend a winter, relax for a couple of months, yes, but living or moving there is impossible. And surely you will not want your children become Thais.
So if you plan to try, go ahead, but do not burn your bridges and be ready to return.
