I remember growing up and seeing unpleasant shows on CBBC and CITV during the 80s and 90s that looking back were pretty heavy going, especially for kids.
Ones I remember we're children's ward. Especially when the girl (who ended up playing Maria in coronation Street) died.
Also this one called Dramarama with one off stories. I remember this particular episode about a boy who steals a rabbit and his dad thrashes him with a belt.
And this drama called the secret set partly in Eastbourne where these kids mum goes missing.
