This sounds like a silly question as I type it, but has anyone found fasted morning workouts to be a cause of anxiety? Will I ever be able to do them again?

Backstory: I had low levels of anxiety for a while and things certainly built up over time, but anxiety slammed me one day after a few weeks of build up. At the same time I had been exercising every morning, fasted + pre-workout with 100mg caffeine, 5-6 days a week for about 6 months. I stopped those fasted workout and quit caffeine ever since (plus got on Lexapro). Now that I’m stable, I would love to be able to do those early fasted workouts (no caffeine) again because I have kids and makes life easier, but I’m terrified that it will lead to anxiety again (messing with the cortisol spikes). 

Thoughts? Experience?
