Change is unknown and we, as human beings are afraid of unknown, being therefore afraid of unknown.
It is normal, because what will happen is not something sure, you don’t know know whether to trust it or not. You know nothing.
But have you ever thought that it is all about you? Whatever happens depends on you.. on your attitude towards that thing?
If you’re negative, then obviously there will be a negative effect, but if you’re positive and you overcome it, then nothing bad can happen.
Change is good, it may not always be easy, but it is good and only you can do something about it, through the way you deal with it.
