Anger Problems ?

I have a sister that is 17. She’s a junior in high school. I just turned 19. I’m a freshman in college. I live at home so I live with her. She has been through a lot of struggles and had many let downs and so much. She has been bullied alot(it happened years ago then stopped but now for some reason i guess its starting again. She didnt have that many friends in graded school but since she’s been in high school she has had so many friends which is good. About 3 years ago, she volunteered at a daycare for almost a year but then the daycare provider died and the daycare shut down. I think all of them were like family so to this day she is still extremely affected by it. We tried setting up her volunteering at other daycares but it didnt work out and her problem is her daycare so not just any other daycare or kids can replace it. We’ve also had a few family deaths. And also our parents arent always the best and i dont really know what else but she’s just had lots of struggles and let downs. Oh and she also has severely untreated ADHD(and no we cant get it treated because our parents dont think she has it and dont want to believe she has it) and dyslexia(and the same goes for this) and im not sure but possibly autism. And she has a best friend who she has known for a long long time and when they were in 7th grade they were told they couldnt be friends anymore by her parents pretty much(long story) and now in the past year or two they have slowly been becoming friends again but parents didnt really know but they have told parents just recently and are now completely best friends again and they are allowed to be. But also recently this girl(my sisters best friend) has been making some really bad choices like smoking, drinking, cutting, and sneaking out. My sister and her love each other and have been through too much together to not be friends so not being friends is definetly not a choice. And she also really needs a job and she has been trying but just hasnt been hired and hasnt had any luck i guess.

She is physical sometimes when she gets mad. She gets mad alot. She has punched a wall and a metal door a few times and hurt her wrist pretty bad, she hasnt hit anyone yet i dont think but i can tell she constantly wants to(she hasbefore a long time ago and i think shes learned her lesson but it seems like she going to breakdown and smack the shit out of someone soon which i dont want to happen). She yells alot out of anger. And she gets really impatient sometimes and i dont even know what else but she definetly has problems and pretty bad anger problems.

A little over a year ago, she was kind of like this but not as bad and our cousin(who lives with us and is the same age as me) talked to her and this is what happened;

My sister was very mad at him about something and this is what they said;

Sister- Give it a rest(cousin was talking about her anger)
Cousin- Listen I dont blame you…if i’d been through what you’ve bad through
Sister-(yelling) thats not it…thats not it
Cousin- Isnt it? Look whatever it is you cant keep it all inside. Believe me, i’ve seen that feeling…
Sister- So now i’m gonna here some sob story huh?
Cousin- No you’re not…most people havent been through a third of what you have…but it doesnt mean we dont get it…and that we dont wanna help
Sister- Are u done?
Cousin- I get the anger…i just wish i could tell u it’d make things better…like bring back the daycare or(i dont remember what he said here) then after that he just stopped talking for a minute and looked at my sister who was kind of turned around and then he just walked away and we noticed an imediate difference how she was a lot less angry(i dont know about happier but she really improved from that talk). And she was good for a little less than a year and now shes worse than she was then.

She used to be and sometimes still is really really happy, funny, goofy and like one of a kind. She’s hard to describe when she’s happy like that but everybody loves it. She has alot of love when she is happy and not angry also.

We are going to try to get her involved in therapy or conseling soon. But what can we do to help her? a talk?(what would we say), behavior chart/program? Or what???
she probably doesnt know why shes mad but im pretty sure its because of all the struggles and problems shes been through

Ask her why she’s mad? Ask it there’s anything going on, or ask her if you can help, but i would recommend a therapist, there’s nothing you can really do, i mean there must be something going on in her head.
