Early sobriety was like having 24 hour per day PMS in a full moon. Feelings all over the place, fear about everything (health is always a good one). What I realized later that, for me at least, fear is about trying to have control. If I keep thinking about something it won't happen. Well, it doesn't work.
My sponsor told me fear is: false evidence appearing real. Perhaps you can step back and realize you have no basis for this specific fear and none of us are good at predicting the future.
You're doing great!!!
