I was very fortunate as a teen-ager. I went to a Catholic school. Bullying was just not tolerated, not by the priests themselves, but by the older lads, strangely enough.
The school I had issues with the two bullies was in a catholic high school. The priests could care less. But I did have to go for counseling with one of the priests like it was my fault. I swear, I think he really wanted to fondle me, seriously, not joking!
That one school year was the worst. I had straight F's throughout the year, why care? Naturally i was kicked off the school baseball team and guess what, I still hate regular sports with the highest passion.
I dropped out of HS and got my GED, five HS's later. I didn't care and guess what, the shool work was easy, I knew it and I could do it with ease. I was not dumb. Did I go to college? No! Did it screw up my continuing education? Yes! Did it affect how my life turned out? Yes! Did it affect my income for years to come? Yes! Do I now have a fantastic wife and 3 great kids? Yes! Would give them up? NO!
The next few years were rough because I had done a complete 180. I was a prick, an azzhole, I dressed & acted like Judd Nelson in the Breakfast Club, I stole, attacked people, got drunk, did drugs, always involved with the cops, felt invincible, did time (8 felony counts) and on and on and on. So those two bullies had a major impact on my life for years after. The time straightened me out a lot and have been basically back to normal since then but I still hold a grudge, 32 years later.
This bullying crap can change the person being bullied. It did me and changed the entire course of my life.
Help your kid out to make the right decisions, I know that is what you want in your heart. It is great that you are there with them, they need the assist. Mine did not assist me through it, I dealt with it on my own and you see where that got me.
