Hi mncjl123, I'm sorry to hear that. That sounds awful.
My mother died when I was 9 after a long illness, and I know what it is like to have strong emotions. I can recommend three approaches.
The first is mindfulness. Passively allow the emotion to come into you and allow yourself to just sit with it. Don't stoke up the fires of the emotion by ruminating, but don't try to fight them. Just allow them and approach them curiously.
The second is to develop compassion for yourself and use that compassion to change the way that you think about the things you feel guilty about. Is there another interpretation that is kinder to yourself and may be more accurate? Chances are, you are being very hard on yourself and causing yourself a lot of unnecessary pain. Developing self-compassion can help you find a way out of this by reframing your thinking about the incidents. The book, Feeling Good may help with this. It's been a bestseller for decades and multiple scientific studies have shown that simply recommending the book has an
effect comparable to psychotherapy or antidepressants.
Finally, you might try looking up EFT as a method of clearing the emotions. (Or, if you can afford it, EMDR.) I don't buy into all of the mysticism surrounding EFT, but it tapping has been shown to be helpful by a number of studies.
If you are getting strong emotions like this, it might be a sign that you want to slow down in exploring your emotions. Better yet, the best thing is to work with a licensed psychotherapist in your state, possibly one who has experience dealing with people from similar backgrounds (people who "get it" like this can be super helpful). It can be really helpful to have someone "in the room" to help balance out your emotions with their own presence.
I hope you find something in the post that is helpful! Not all of it will be, but you can always take what resonates.
