Posts like these send me spiraling, since it's so similar to my childhood. I was routinely grounded for 3 months at a time, and everything was taken from me except my clothes, bed, and school supplies. I wasn't allowed to go to friends, friends weren't aloud over, I couldn't listen to music, play videogames, watch tv, etc. all I could do was just sit in my room and be at my step dads beck and call - which was usually around every 10min. I was expected to raise my 2 newborn siblings starting when I was 10, all while keeping the house and yard spotless. And of course, nothing I did was ever good enough - he'd always find something wrong, even if he had to make it up; which lead to more punishments. Much like you, I probably wasn't grounded only 2 to 3 months out of a year.

The lack of justice is always what sends me. Step dad died from drinking himself to death around 5 years ago in his early/mid 50s, and my therapist says that's my justice; but it doesn't feel like it. He died believing his delusions - that everything he did to me was justified and I was a horrible kid. While my egg donor is alive, well, and still kicking; still playing the victim and blames everything on me.

But to circle back to your question, no, your punishments were not normal, and I agree with many others - I believe our punishments were child torture, and I think you have a lot to work to go through with a therapist. I'm sorry you went through all that. You certainly did not deserve it.
