Well, first of all, i am asking help here, because thiss community gives great 'man to man' advices and besides that, i have nowhere to ask for help.

Nowadays, i don't need any help, i am sorting my self out little by little, but what worries the most is my brother. Day by the day, i fear for his mental and physical health. It brings tears to my eyes, but i fear that the worst could happen to him...

TL;DR: My brother who is going through very hard times might harm himself. I try to help him but he is too stubborn to accept it.

Well, me and my brother had semi-tough upbringing. We were born in a low-class family in Brazil, by two very hardworking parents that tried the hardest to give the best to us (even tought they couldn't most of the times) and that's where the problem starts. As many here, me and him were brought by our mom alone. We did had a father but we barely saw him at home during our childhood, and most of the times when we saw him it wasn't pleasing. He said straight to me and my brothers faces, many times, that he "wished he never had kids", "merrying and having kids were that worst thing that ever happened to him" and that me and my brother "would never achieve anything in our lives" and that we would be "a bunch of shit". Besides hearing this from him, we had to constatly hear our mom ranting about him to us, he talked mostly about how he was unfaithful to her and we had to hear them arguing a lot, and hear him call my mom a bunch of horrible things(verbal assault). My brother had it rougher, besides having to deal with this, he was bullied hard in middle school(knew about this a few months ago), and he still carrys the scar of this till this day in his soul. Through out middle school and high school he put on a lot of wheight and it's obese now and this contributes to his almost non-existant self-steem. But the deeper problem started last year, after he met this girl an dated her for almost 6 months and dumped him out of nowhere to stick with another guy she had known for just 2 weeks. He, after that, was literally depressed and would stay days laying in the bed looking to the ceiling, i even read a post he made in a forum said that "if it wasn't for my mom he would have killed him self" and it seems that he never recovered from that. From this day he was never the same. My brother, even after suffering everything he suffered, was always very light spiritted, funny, talkative and making fun of everything., but since this incident with this girl he looks very shy and fragile.

Not gonna lie i was tough on him too. Me and my brother were neve friends. We never had a tight and hard bond, we never had this "brotherly love" that talked about everything. Most of the times we were always fighting. I am very short tempered(working on this) and said a lot of bad things to him, that now i regret and am trying to treat him better and come close to him, but after so many years distant it's very hard to bond.

He is 25 years old, with a degree in geography from one of the best colleges in our country. He said sometimes that he regreted having this degree and that he doenst really like geography and doesn't have a dream or a purpose in life. As some of you may know, our country is in a horrible economical crisis and jobs are scarse and he is two years unemplyed. My mom manage to get him a job, but he declined saying that "since he had a degree, he is not going to work in a non-degree job that doesn't pay well", we tried to convince him that times are rough for everyone and he should take this job temporarily, but he refused. My brother is VERY VERY stubborn and arrogant and everytime we try to help him, he declines, saying that he doens''t need help and can do things on his own. We tried to talk him to go see a pshycologist but he said that "psychologists are for retards". Yesterday i caught him writing on his journal about not haviing true friend and not fitting anymore in his group of friends, which made me really sad. He basically stays all day in front of the computer watching anime or movies.

I REALLY want to help my brother, but i don't know, everytime i try to help him he refuses or doesn't listen to me. I really fear what he could do to himself. What would you guys to in my situation? How to help him?
