That is so sad! But like you say, excellent therapy writing about stuff like that! We tend to sweep bad memories under the carpet but they fester until it's brought out into the open, almost like a cleansing, so steemit is an excellent platform for memories like that as it probably will only be seen by a handful so it does not really matter, but you got it off your chest and it's in the open!
Strange how complex some relationships can be!
If you ever get the time do yourself a favour and google Mark Wolynn who wrote the book 'It Didn’t Start With You: How Inherited Family Trauma Shapes Who We Are'. There are some youtube videos available on his work.
Then there's Family Constellation Therapy as well.
It's very interesting how 'unfinished business' is passed on to the generations to follow so we should all put pen to paper so to speak and not hide stuff that's whispered behind closed doors but festers all the time!
