My parents dont believe me when i think i have a problem.?

bassically my parents think that im this perfect child and when i f**k up they freak outt, like they have no idea what is going on with my life. they have no idea that i used to slit my wrists everynight and have wanted to kill myself for alomst a year. if you look at me and see how i act you would have no idea that im a completewreck but inside i am and not even my parents can see it. asside from the fact that my relationships with guys make me crazy, im doing terrible in school and i cant help it. i try so hard but i cannot concentrate on my work bc my mind is thinkning about a million different things and all of my teachers and friends think that i have some kid of ADD but my physco perfect parents dont believe it and as much as i tll them i need to be tested they just dont beieve me and i cant do it anymore im sick of failing everything and not knowing what is going on bc i completly zone out in class no matter how hard i try to focus. I JUST HATE MY PARENTS.

Part of your problem is that this is not your problem. If what you say is correct (and this scenario is not uncommon) your parents' narcissism extends even to their kid. They take it personally when you do something wrong because of THEIR need to be perfect.

Your parents don't seem capable of offering the support you need. They freak out when something goes wrong but when you TELL them something is wrong, they refuse to believe it. This is a shame. So many parents complain that they get shut out by their kids and here you are inviting them in and they won't listen.

Is there someone you can turn to for support? Your school therapist was suggested. Perhaps a guidance counsellor. Someone in the family or extended family?

As a rather extreme alternative, you could get yourself checked into a hospital for a while. If your parents have good health insurance, you could get some quality care and the testing you mention. You might also get a doctor or other competent practitioner to encourage your parents to focus on your well being rather than on their need to have the perfect child. Tell a teacher or counsellor at school that you have been cutting yourself and it's getting worse and you are afraid because you know you're going to hurt yourself seriously.

An adult could make an appointment with a mental health practitioner and ask for what s/he needs but you made it pretty clear you're crying out for help and nobody is listening.

I can't possibly know your entire circumstances but I think if you believe you could use psychological help, you have a right to be supported in this.

well how old are you? when i was a teen i had the SAME things going on. no one ever knew how i felt and what i was doing cause i hide it so well, i didnt get help until i was in my early 20's and they said i am bipolar, and have BPD. these are things you might have going on with you, kinda sounds that way. talk to your school therapist, or try and get your parents to understand, but you have to tell them your cutting and what not, make them listen. good luck!
