Can pictures and family photos trigger a manic episode. i feel like they do for me. ?

You know best!: If there's only a 20% chance of rain and it does - you still get wet. If you've been diagnosed as having a type of emotional illness that features manic episodes and you've noticed this trigger, I expect you're right. Other things may too - even no trigger is possible. Experiment by avoiding exposure and see what happens. That sounds possible to do. Best wishes.
