Is this the right approach? It's all I can think to do.?

Ok, so, my parents have never been understanding. EVER. They think i'm a attention seeker little emo kid. And when they want answers as to why i feel suicidal, they come in DEMANDING it or yelling and...well, sorry, i'm not gonna answer things that way. Momma demands. Dad yells. Elsewise, they complete ignore it. Like seriously. I went to the school counselor begging for help, and she called me mom like 6 times reporting this because she watches me around the school, and my parents never said a damn word to me other than "You need to stop. Your counselor won't leave us alone"
I'M LIKE, ARE YOU SERIOUS?!?!?!? MAYBE just MAYBE that's a SIGN you know?!
Anyways.
They don't really do much. I've cut myself for years and every now and again they search my room and take out any razor blades or whatnot. Never say a word to me about it, I just notice their gone and role with it.
I overdosed before, last year, and they would barely even sit in the hospital room with me... Momma just yelled and dad went into police officer mode when I needed my daddy. He's a cop, btw.
Anywasys...
So here, this past like 2 weeks...I've been completely suicidal. It's all I can think about. I want it, so bad, i've cut so deep I thought I was going to die... but I'm a pus. I can't get it right. I want it so bad though. I'm gonna keep trying, I know.
Because I haven't been able to sleep well, or eat well, it's taking its tole on my body. I've been home from school for two days. Dad said "You're either better tomorrow or we're taking you to the docttor." Like that's a threat >.> .... Anyways. I can't get my mom to vacate the room when i'm at a doctors office, and she changes EVERYTHING i say. Downplays it or says "NO YOU HAVENT!" and i'm like...really mom?! REALLY?!
And i know you'll say "TALK TO YOUR PArENTS" but I can't, and I have no one to actualy talk to about any of this..

So, i'm going to the doctor tomorrow about my physical illness. What I plan on doing is sending my mom out of the room (wether she likes it or not!) and telling the doctor EVERYTHING. Like suicidal and all....
I don't know if it's rihgt, but it's all I can think to do honestly. It's going to make my mom beyond upset if I get sent off and i didn't say anything to her about it, or they'll think i'm begging for attention...either one. But I can't talk to my parents! So I seriously don't know what to do about all this. It's crazy. I see no other choices...
If you do, PLEASE tell me.

Yeah, it sounds like it's best to tell the doctor everything you dare speak about. At the very least it will get it off your chest, and that'll reduce some of the stress.

Just a tip: the doctor's only human. So I suggest that you make a list of single-line (less than twitter-length) notes on your computer and then, after you've got a dozen or so, sort them by priority, and group similar items together. Keep typing notes and sorting/grouping them until you're out of ideas about things to write down.

Why this extra effort? This way you'll be able to tell the doc the maximum amount of information in the minimum time, which means he or she will have a better idea of what's up. If you just say stuff at random you make his or her job much more difficult. The quicker he or she gets the big picture the more time he or she has to work with you on the issues.

look here you. you will be 18 soon and they won't have such power. I would tell the doctor, then get into therapy bc I bet there are other issues underlying. Your parents obviously have issues too, which leads to the next generation being screwed up. If you tell the doctor or any of his/her staff that you want to talk to them in confidence, they are really good at getting the room cleared without being rude or upsetting your mom.
