Sounds like you are just afraid of what might lie ahead.

This feeling is not just reserved for people with emotional/mental illnesses - it happens to everyone who has to deal with any big (and small) changes that will deviate them from their current "routine."

I know this is a general statement, but then again, so was your post.

If you give more details, some of us might be able to provide more details about our experiences if they closely match your current situation.
