How Do I Tell My Parents They Were The Reason I Wanted To Kill Myself?

I have been going trough a lot, and I told my mother a lot of time she didn't seem to understand it clearly, but when she talked to my father he tied his best to get me help I got a therapist for about one month she didn't help me that much because I still hurt myself, the reason I got the therapies is because I told my father (which was a 20 years recovering drug and alcohol user, that also have my problem but much worst) about it e took it very seriously and didn't judged me, after one month of her giving me advise I stubbornly didn't take the advice, but the thing is, my father got anger issues and my mom was a bit judgmental because she didn't understand why I'm feeling all the stuff I'm feeling, but after my 13 birthday things have been worst, my parents treat me like I'm a nine year old, when I act out they would just yell at me, I have gotten a lot more emotional which wasn't helping the case, before I just dont think the worlds needs me, but now its just the feeling that I'm a frailer and I shouldn't be at the sight of my parents it will make them look worst they can be mean I am not sure if I think my parents are good or bad parents because they made it hard for me to, the reason why I wanted to kill myself because of my parents is because they have been yelling at me and no one's like that especially me I mean I am growing up I'm technically a teenager and they just don't understand that, they dont care about my opinion they never did, they dont care about my privacy, they dont care that I'm growing up, they dont care that I wanted to kill myself and have told them before that they are partly the reason but they seem to not care ad is still making me feel worst about myself and I just don't think this can go on any longer, I now cry every single day because of them and my anxiety, I just dont understand why they are offended that I told them that they are partly the problem and not trying to help me instead or maybe change just a little bit, don't get me wrong, I love them they are good people but it's just that I feel like if this keep happening I may have kill them one day, I don't want that and I bet you they dont want that either, I just need some answer because I dont know how to tell them these things, I did told my mom a few times and she's just offended by it and not at all sorry, I just want a good way to tell them without making them mad or pissed at me.
