I agree with you about "was nurturing."
I think you mean, "I now
have 24 hours a day . . ."
The logical connection between the first and second sentences is weak. What do you mean to make of the two time factors (
passed, and
now)? The reader is expecting a point. Are you possibly saying that when school let out and your vacation began, the summer was already half spent? You need to make it clear.
