It's been a long time since I triggered, @PeppyPatti, and my triggering may have been different to yours, but I learnt to ride it out, distract myself—clean, tidy, go for a walk, sit in the sunshine, garden—distract myself with simple tasks. It enabled me to grow stronger. Triggers will always be there; for me it was a matter of negating them with new life goals—meaningful ones that were in the direction I wanted my life to take. I have never seriously dwelt on mental health reading because it becomes the default way of life and precludes change. It's just the same reading, over and over. Stop looking for what's wrong with you and build on what's right with you.
Sorry if this sounds too simple, but it's difficult to put ourselves in another's shoes and come up with the right suggestions.
