Is it ok that I'm completely scared of the unknown?

My life has changed so much, I feel like each day, hour, even minute that passes I become a different person. Is it constant growth or is it the fact that most of my life remains very unknown at the moment. Where will I live in 6 months? Will I be able to finish school? Where will I be working in 6 months? Will I be in a relationship in 6 months? It scares me. All I do know is I have a beautiful awesome little baby girl that's going to be tagging along with me and that makes me happier than anything has in a very long time
