I am become so angry and bitter. My brother is having it all while i am at a spot without making any progress 
That's really tough. I can imagine how frustrated you are. Just know that going through trials and struggling is always good for your character and you will end up that much better of a person for getting through it. You can't be too concerned with other's lives, you just have to try not to compare. 
I am trying my best, but he lives so close to me and i can see all the progress and my mother do the comparison too. Everyone does it 
Oh well that's too bad but their behavior is not right or fair, and they will deal with the consequences of that themselves. Forgiving them is good for you and for them. Just try your best to let go, I know it's tough- but people everywhere are way more successful then you and way less successful and you don't compare yourself to them I hope so why focus on one random guy just because he's your brother.
