Is it normal for your parents to pop your pimples?

I’m 19 years old. Ever since I was about 13 my parents have OBSESSED over my acne. They usually sit down 1-2 times a day for 15-20 minutes and go over every square inch of my back. They pinch every spot with their nasty, grubby fingers because “you have to get the poison out”. They don’t stop until the spot begins bleeding enough to pour a little because “it ain’t gone unless it bleeds” (yes, they are that fucking stupid). With the larger ones, they use a small sewing needle to dig it out to make sure nothing else is in there. Then they warm the tip of a Bobby pin by cigarette lighter and touch it to the sore to “sterilize it”. Until I was about 15 I used to get terrible blackheads all over my nose. They would spend forever squeezing every bit of it out and collecting it on a paper towel. I still have a scar on my nose where I bled really bad, and my pores are really stretched out (I still get blackheads, but not as bad). They get absolutely irate if you try to argue with them. I remember one time, I was about 14, when I argued with my dad over it while he was in the middle of doing so at the dinner table (fucking gross, I know). He was (basically still is) an alcoholic and he got so pissed he flipped the recliner and trashed most of the house. He spent the rest of the evening telling me I was a worthless piece of shit. The last time I was at the doctor’s I had to remove my shirt and they seemed sort of concerned about the scarring. They did tell my mother that the sores should be left alone but it did nothing to stop her. I’ve tried sacylic acid, peroxide, and sea breeze but nothing works. I was talking to a couple other people my age online the other day and they told me it was not a common thing at all for your parents to pop your acne, especially not so obsessively. Has anyone else been through this?
