how do i approach my fp and tell them that they said something that hurt me so bad it caused me to have the worst day of the past 3 months? 

i don't even know if it's worth it to say anything about the subject now that a whole day has passed since the incident(s). im stable now but i had a rough day (rapid cycled for probably 5 hours). should i just move on since im stable now and not re-stir the pot unless he says something similar to what upset me? now that i have some hindsight i can approach him in the moment better if it happens again :/ 

idk i don't want to stir the pot and i definitely don't want another day like today and i feel like if i brought up this issue it would just cause me to be upset for another day and him to resent me for even speaking my mind. things have been tense between us lately, i believe it's purely stress from our jobs and not relationship-based. i did tell him today was the worst day i've had since october, if he asks me about it maybe that would be a good cue to speak on the subject?

unrelated but i felt i should include: i sent him some youtube links about fp and managing fp relationships and said i was going to work on the things the doctor said in the video and i just wanted him to watch as well so he could have some understanding on how i see the relationship. hopefully that doesn't upset him, for me to openly admit to him that he is my fp. 

i am posting this right before bed but i promise promise promise i will read and reply to everyone. i will probably be afk for at least 10 hours
