What you've describe about your brother's crying sounds just like my 7 year old son. He has always been an easy crier. He cries for the simplest things. He is also having the same issues at school. I get called almost everyday because he is having a "meltdown" (crying, screaming, refusing to do work) and they have know idea as to what "set" him off. I can't say for sure that your brother has the same thing my son has but it is worth looking into.
My son has been diagnosed with Social Anxiety Disorder, Obsessive Compulsive Personality Disorder (not the same as Obsessive Compulsive Disorder), ADHD-mixed type and Mild Autism.
He is taking an Anti-Depressant, Mood Stabilizer and an ADD med. We have seen a Psychologist, Psychiatrist, and a Pediatric Neurologist. Maybe you could tell your mom to try getting your brother seen by one of these. They would be able to answer a lot of your questions.
These are behaviours common to anxiety and/or depression. You might wish to google the phrase "anxiety in children" or "depression in children" to see if any of the descriptions remind you of your son. Another possibility - is your son being bullied at school? Anxiety and/or depression are common behaviours to children who are bullied. If you think that anxiety and/or depression might be the issue, the first thing you should do is to contact your son's physician for advice. Just wondering ....
Maybe you misunderstand me, i do not intentionally look at him in in a way that would make him upset i'm just a generally ugly person and he sits around till 3pm on weekends refusing to get dressed regularly. Besides it's not me who tells him to get dressed anyway it is my mother, the majority of this is taken from observing him. Moreover he is told to speed up because he does everything so slowly getting distracted by anything and everything so long as it is not what he is told to do. We have tried to find out what makes him upset but there seems to be no central reason for it and i'm just worried that when i comes time for him to go to secondary scool, he will be eaten alive
Why not help your brother, it sounds as if you have a jealousy problem with him, evrything you said was not kind at all, why not help him, perhaps your parents need to check on who is making him unhappy , why do you need to tell him to get dressed or to "speed up' and why would you look at him in any way that would upset him.
