My Brother Will Make Me Cry To My Dead Parents Against Him

hi family landers,

I am so depressed as of right now..

I have a bro who recently got married to his fiancée..

we were happy as a family until my bro's wife started interfering in between my bro and I..
it all started when I had an urgent need in school, I approached my bro with the most humble scenery one can ever imagine, his wife just cut me short, and said they was no money, I was shocked as my bro sided with her and said they was no money.
I took it in good faith and went away.
later that day ,when they were back from work,I overhead my bro talking to someone in his bedroom..
I went closer and behold my bro was talking to his wife sis asking her if she had seen the alert of the money he sent to her..immediately I heard that,I just sat on the floor and sobbed loudly..

I wonder why my bro will be treating me and my junior bro like this ,we are orphans (lost dad and mum the same day in a car accident)my bro is in jss3 in a public school(my bro's wife changed him with the pretext that they couldn't afford the private school fee).me,I'm in my final year in the university, just remaining my project and my final year school fees..
I am really depressed as my mates have already gone to nysc..

I can't go to anywhere because of clearance and my bro has turned a deaf ear to my appeal to set me up with something I can do to at least clear my self in school..
I am not a lazy person, God forbid that I be lazy but I don't have the necessary incentive to startup something..

I am just fed up with the whole scenario, I have thought of suicide, but ithat will be foolishness as my junior bro will be left in this world to suffer alone..

If my parents are seeing all that is happening, they should please intervene on our behalf because I'm almost giving up... ;'(

sorry for bothering you all with my trouble
