You are not coming from the state of having it, but more from the state of wanting it, but being afraid that something goes wrong on the way. If you were in the relationship, you wouldn't probably feel anxiety after a phone call, right?
"Self-abandonment. That is the secret. We have to abandon ourselves to the state, in our love for the state, and in so doing live the life of the state and no more our present state. And to make the state alive, one must become it."
Neville Goddard ~ The Law and the Promise
