i know it’s wrong to avoid your theme but also my dad just chatting about suicide is not helpful to me at all.

It’s a rough trigger don’t be too hard with yourself you’re slowly exposing and learning to handle your harm OCD. Self compassion :$)

It may also be worth considering whether part of the issue is the way he's talking about suicide. Like race, religion, politics, gender, etc, suicide is a really sensitive topic. Many people (unintentionally) discuss it in ways that are disrespectful and damaging. For suicide, this might sound like: -"Just shoot me" when someone's frustrated -"people who attempt suicides are cowards, they take the easy way out" -"suicide is so selfish" -"natural selection at work, eh" These kinds of comments elicit strong emotions. If your dad is saying these kind of things, a healthy response from you may include pointing out that he is being offensive and educating him (if you think that could be effective) or setting boundaries about not discussing suicide with him (you'd need to clearly state that you don't want to discuss suicide with him and then leave conversations if he brings it up)

My sister has a habit of talking about extremely triggering things around me. It's not something to avoid but it still upsets me a lot, she does it when I'm stuck in a car with her, or loudly outside my bedroom door. She's talking about those things because they're relevant to her own life, they're not aimed at me, but we have had some very similar experiences and I developed PTSD whereas she didn't, which she knows. She also talks a LOT in general (she has anxiety) and is young, I wish she was just more aware of the impact and have these conversations in a way that is more considerate, but I have also found it very difficult to make her aware of how this affects me- I don't want a fight about it.
