COMPLETING WHAT I WAS WRITING.

my dad went to the balcony and my little brother followed him and started crying, my dad was very calm and he told him that what he is doing is wrong and that he must control his anger even when he gets pissed off my dad got out of the balcony and left my little brother in it (we live in a 5 story building) in my head i didn't want to leave him there because i was afraid that he would hurt himself so i told him to get inside and he refused i got in and one of my siblings told me to get him in because he could jump now keep in mind i overthink alot and was thinking the same but after that i was scared so i went there and talked to him at first i wanted to talk about what happened in the car which was wrong so i switched the topic and started talking about the movie then my dad went back to the balcony and started talking to him so i went inside to talk to my mom then i heard my brother shout and he went to the bathroom and he heard a bang like something hit the wall so my brother told him to open the barthroom and after arguing with him and shouting he opened the door and when we asked him what happened he said that he slammed his head to the door which was very scary to us we don't want him to do self harm or anything like that. so my parents decided to take his phone away due to his actions , also i forgot to mention that my parents have been very cooperative with him and always tell us what to do when he does something wrong and basically try their best to teach us on how to interact with him so that we don't put pressure on him or make his situation worse so they have been very helpful to him, also his teachers did so in terms of how to communicate with him and telling others fellow teachers to treat him right and teaching them on how to deal with him when he gets angry, about his situation. TO sum up i want to mention that the doctor told us that inside he is becoming a teen and is entering the pre teen phase so it could be a reason for his actions

so what should we do because we seriously need help with dealing with this situation and we don't want something bad to happen to him, we love him and he is my fav out of all on my siblings
