Great that she's able to go at your pace and not hers, i could imagine it would take a lot out of you to be dealing w/ finding yourself more easily triggered, i hope you'll keep being able to see yourself getting overwhelmed *before* it happens, maybe you can't control stress from outside sources like work, but at least you can still recognize that "full steam ahead" would probably hurt more than help for now... and maybe the "lake" thing might help if you have a shot at getting (or insisting on) some quiet time during breaks, lunch, etc. so your workday doesn't totally own you, memories surfacing is no joke- take your rest when an where you find it. I'm rooting for you bro, keep doing what you need to do...

Give sorrow words: the grief that does not speak
Whispers the o'er-fraught heart and bids it break.

-William Shakespeare, Macbeth, Act IV, Sc. III
