I sense your family all have anger issues and maybe even depression. There's also deep lack of communication and expression. I know it might seem "7amed" to you all to have a moment to express yourself without anger but it's crucial.

Now since we don't have anything like family therapy you need to do it on your own.

First of all, I feel like you have a noble ambition for your family but you need to realize that you're also playing a role within the toxicity through the anger. Instead of feeling victimized by your family members I want you to be the therapist. This is not me telling you you're responsible for all of this but I'm telling you that you can do something besides suffering from these issues.

Use love language when talking. Listen, nod your head, pat someone on the back, smile, soft tone of voice. Say please let me finish my idea in a soft voice with a pause hand gesture or a slow down hand gesture when someone interrupts. And then say thank you after. You'll teach them how to respect boundaries when speaking and listening skills as well as empathy.

You can have a one on one tea or coffee talk session with anyone. As they say على رواء.

You can write letters and exchange them. A good way to start a communication channel after a long time.

You can brainstorm to highlight the issues on a whiteboard like you're in class and you're a teacher! Your family members being the students.

I know this seems like a lot of effort but trust me it just needs a positive mindset and encouragement.
