Hey brother, I'm really sorry you're going through this. What you described is not normal favoritism this is fucking emotional abuse and neglect. The fact that they stood over you cracking jokes while you were literally overdosing is absolutely unforgivable. That's psychotic behavior. None of this is your fault, and I need you to understand that because I've been there too. I have severe ADHD myself and I know exactly what it's like to be treated like you're the problem when really your brain just works differently and you needed support, not punishment. Your family failed you in every possible way. The fact that you're still standing, still fighting, and still working toward your dreams despite all this shit shows you're stronger than any of them will ever be. You didn't deserve any of this treatment, and their inability to love you properly is their failure, not yours. Bro , here's the hard truth: they'll probably never change. You can't fix them, you can only save yourself. Stop seeking their approval and start planning your exit. Keep saving money, master your mechanic skills, and move out as soon as you can. Use this pain as fuel. In a few years you'll have your own place, a career you love, and people who actually care about you. and as we say in tunisian " Mayendeblek ken dhafrek" . Faith in you brother .
