I seem to understand what you mean. A couple of years ago I was in a very similar situation. From the whole gamut of my emotions - doubts, longings, feelings of guilt and stress, I realized that everything is right in my life. Any event or action that we perform is correct. Just accept that you are here in this situation. We tend to get used to what we do and what surrounds us. Feeling doubt and stress when something changes in life is normal. However, it is wrong to consider these doubts as an indicator of exactly the wrong choice, error.
