There comes a point in your life when you have to take a decision, firm one. You take it, stick to it, execute it. You might alienate some people with your decision but as long as you know the decision is right there is nothing to be concerned about. If you have the slightest doubt that the decision was wrong and it has done more harm than good, you must rectify. If you are sure the decision was absolutely right then you need not be worried about the people you alienated, you are better off without them in your life. If people cannot appreciate you for what you are, you don't need their drama in your life.
