Liam/Mario_Sonic,
Thank you so much for sharing this here, welcome to the forums. Oh goodness, I can only imagine how devastating this has been for you to go through. On top of it all, to be having nightmares as well, those constant reminders must be taking a significant toll on your mental health.
Off the bat, it's good to cry. When your body feels like it needs that release, it's important to listen to that instinct. It's how we can process grief and things that are upsetting. Some other things you may find useful to do may be to journal about how you're feeling, express yourself in a creative sense, exercise, take a brief walk out in nature, or even do something like write letters to loved ones you've lost or look through photos. Listening to what our bodies need when we're grieving is very important. As somebody who also gets nightmares sometimes, I find these things very useful.
Have you considered speaking to a counsellor about how you're feeling? Not sure how old you are, but it sounds like you may be school-aged, and school counsellors can be helpful if you're wanting someone to talk to.
I hope this helps, and please feel free to keep chatting with us if you'd like to.
All the best, SB
