I was a horrible student in any class I wasn't comfortable in (most). It's crazy looking back because I didn't realize how checked out by parents were. They didn't know how I was doing in any classes unless they got a call or the report cards came in. My grades started slipping when I was 11 and my only friend ended the friendship and joined a group of friends without me. If I liked the teacher, I usually got A's. If I didn't, it was D's and F's. I wasn't asked what was wrong at any point and my failing grades were always met with punishments, anger and being grounded. I was grounded so often, I couldn't make decent friends unless the friendship could exist just at school. I ended up befriending another girl from an abusive household who also couldn't have after school socialization.

There was never any mention of tutoring, my mental well being was never considered (my mom once found me writing a suicide not, claimed it was hormones and because I didn't want to do my homework and left it at that), I barely had any wearable clothes and for a long time, I was using my white marching band uniform shoes as regular shoes because my parents didn't notice I had no other shoes and I had stopped asking for things like that long before.

I've always fully blamed myself, but as I'm getting older, I wonder what the heck my parents were doing being so clueless. This whole post could easily have come from my parents who were big believers in personal responsibility and in punishments as corrective measures.

OP, there are many ways to teach a child. If your go to is punishment, at least consider other options. Make sure everything really is alright. Never punishing a child can be a poor choice, but consider this:

The whole world will be happy to punish your child for the rest of their life when they mess up. They only have a limited number of people who should have the time and concern necessary to help them without punishment when they're in need.
