I Still Can't Make A Decision

I need an idea - how to estimate how much to stay in this job I currently occupy. I had a similar experience and although after much deliberation I decided that I should change my job. I wanted the change and I knew that nothing was holding me back from the job in question. Now, however, the horror is complete. I work in a field that I like. But I have no chance to realize my potential. I have been working for almost two years now, but there are still liaisons, retirees with preferences, some family relationships - likes, dislikes and everything else, but no rules. There is no company strategy for evaluating a person's qualities. The people who are your direct managers are very elementary and mediocre and there is no practice in the company to value the person as such. What do I have to think then Well, the area where I work is in my blood, and this is stronger than me. And instead of the employer using this - he is not interested in it at all. It relies on mediocrity. At the moment I am not able to find a company with this type of activity, and to stay in this company is a waste of time. What to do? Give me an idea how to convince myself and get away. How do I test the employer and find out if I'm right in my reasoning or if I'm mistaken. How do I know if my colleagues value me as a colleague or if they don't care at all about my presence on their team? I just feel a disrespect, a disrespect for the work of the other, a disrespect for the contribution of each member of the team. It all ends with the phrase "there are no irreplaceable people" There comes a moment when I get dumb, I feel affected by the fact that I work, and this work is not valuable and even worse - it is not appreciated. It's awful to do something which you love and to be among people who are alien and indifferent to you. You talk, you communicate, but there is nothing real. You should always remember and be aware that you should not rely on anyone.
