BF's brother "tried to commit suicide" for the 3rd time last night... And put a video of it on Facebook

This attention crap is pissing me off. It's deeply affecting my BF and his family all because the kid wants some attention. All he ever does is barely cut his wrist and then shows people. If he wanted to kill himself he'd do it. There are plenty of ways in that house. Stop seeking attention. And I'm not trying to be insensitive on such an important issue, but this crap has to stop. The man is 34 and has enough attention from his mother to gag. She's half the reason he is like this. My family has been affected by suicide and I know what a tragic, serious subject it is, which is why it pisses me off that he uses it for attention. We continue to bring him to the psych hospital every time just in case but enough is enough. I'm so annoyed but don't dare talk to my BF about how I feel. He knows it's for attention as well but I just try to be there for him.
Last week he told my BF for the second time that he wishes he (my BF) would have been shot my Osama bin laden when he was in Iraq
😡 😡 and then punched 12 holes in OUR house. We are letting him live there because he has nowhere to go and that's how you repay us? He doesn't value belongings because his mommy still buys him EVERYTHING! I'm so annoyed and pissed off over how this is unfairly affecting my BF right now. He's trying to work a full time job, go to school for a chemistry degree full time, take care of his brother, tolerate his crazy mother, all while trying to manage a LDR with me and come see me whenever he can. I just feel terrible for him. I want to slap his brother and tell him what a selfish idiot he is. Ugh I'm so mad

I'm sure many of you will give me slack for being mad about this or tell me to take it more serious, so I'm telling you that it's being taken serious and he's in the psych hosp right now, I just need to vent my frustration. Sorry.
