Try to talk to my dad again without slam the phone down

I spent too many years fighting with my dad and my mum…
My life was not so easy, but I don’t want to talk about this now and here. The thing is: I can feel my brother’s pain but He doesn‘t talk about this with friends (like I do), and it scarries me, also because I’m shure that this suffering is making his problems worse. So, trying to get the situation better, I called my dad over again. But it seems doesn’t work…
