Can relate to what your saying, my current situation is very similar. What your friends and family say is completely predictable and parrots the propaganda instilled through years of conditioning.
Using the word "dark" in JW speak is always negative and is used to imply that what is influencing you must be coming from a worldy even demonic source. Remember, there is never a legitamate reason that you could possibly have for "leaving the truth". For many their fear is real since you are choosing the other path, since there are only 2 paths. But it is understandable that having come out of a "black hole" where clear thinking and reasoning are verboten, that it is going to take time to regain your focus and adjust to the light.
You don't have to immediately jump on another path.
