Sorry to hear you are having a rough time.
Not to sound hokey,and probably easy for me to say,cause I haven't hadn't had many dreams come true.
If possible try to realize the flips side,that you had at least experienced your dream, being in acting, think of those that never get that far, never knowing what their dream(s) would be like,constantly striving and never, ever getting the chance.
At least you have had the experience, maybe you can step off your dream for a temporary time and pick up some other type of work while keeping still keeping on call in the acting world.
Just a thought.
Lots of luck with this all.
