You are PERFECTLY like other people. You are needed to be cared for and treated like a normal human being. You going to private school is not the only reason why you are smart, I know you may think it is, but it isn’t. Do you study hard? (If so, then that is why.) if not, that is natural smart. Either way, you matter and what they said isn’t right. Also, even if ur just a little overweight, you are still a human being. You are perfect. It doesn’t matter how your body is shaped (unless it’s SUPER unhealthy, I don’t want you to die.) of course, your hobby is special. Crocheting takes time to learn, you cannot do it in a second.
For your parents, please try talking to them. I wish I could be there for you While you are talking to them. By the way, you are not a loser or a manipulative individual. Your dad may be right though, if it’s something bad, do try to fix things (like if you hurt someone, Yk?)
Oh dear.. sorry if that part hurt you.
Keep in mind, if you ever think of harming urself or offing yourself, please remember there are people who care about you like us. Some of us may not know you personally or physically, we still care.
