Due to our misunderstanding, I really feel depressed.

Good day airasheila hope you feel better soon. How old is your brother by the way? I understand how you feel but sometimes we cannot force them to do what we tell them to do. We cannot put it into their their heads what we think is right for them. It is how they think and how they take things their ways not ours. We cannot force them to follow us what we wanted them to do. Maybe your brother respected you only that he does not want to do things how you wanted it to be. Even though you did not tell us how it all started your age and your brothers age and the gap between your ages. There are times that we let emotions rules us that will lead to heated arguments and depressions but do not let it pull you down instead take the lessons you can learn from it at use it to correct the misunderstanding and bring you and your brother back in good terms.

Elder sister-- you have not given your age in profile --In case your brother is married , it is better not to give more suggestions to him. also we should be aware that we have a right to suggest. it is for others to accept or not to accept. same is the case for the words of your father also. so please do not feel bad. he is normal. your expectation is probably more. reduce that. then problems will not be there.

I don't know how old you are or your brother or what you were fighting about.But,if you are both adults then that does not mean that he disrespects you just because he does not follow your advice.;

dont be pissed off in first place and dont feel sad or upset,just try to sort out the misunderstandings and talk out your mind to them and as time goes by ,they will be back

No matter how we fought with members with our family , at the end of the day still , no one is there for you but a family. Have a heart to heart talk with your brother, speak so gently slow but stress those important point , now if he still remains disrespectful to you , don't force him to follow you , leave him ! That bother will realize sometimes to the things thet he been doing. Sometimes also it is a stage of teenager being so hard headed and attention seeker. Sometimes no matter how you force and insist things , still they remain as is . Be patient for its a phase , that stage will pass.
