As someone who as been in the same position, you are absolutely in the wrong. After barley making it out of high school, I spent all of my summer in bed all day. I didn’t work, and if i did it was for my parents farm. I tried to commit multiple times.
When you don’t feel like you are being appreciated, you fall deeper and deeper. It’s really hard for those without a mental handicap to understand. You can’t explain how you feel because you yourself don’t understand it. I think he needs some psychological help and you need to rethink the way you’re raising him. I’m so very thankful for my parents changing their ways, i wouldn’t be here if they hadn’t. I know the frustration you’re feeling, my mom felt that too. And sometimes it makes you feel like you’ve failed as a parent. Regroup, redirect, and retry. Never make him feel like he is not important. When you’re this low, even just a smile and reassuring comment can change your life’s outcome.
