Depression/ BiPolar disorder?

I need help. I've been looking all over the internet. I've taken hundreds of online tests about bipolar disorder and depression because I think I have a serious problem, but no one believes me. The tests I've taken don't seem specific enough, though. I've had a history of depression, and I think it's coming back, but worse. I'm having mood swings. Just today I was sitting in the car with my mom and I got all hyper and antsy, but there was no reason for it. But something made me really mad and my mom was really worried because I was practically yelling at her, but I don't know why I was so mad. I've been having really bad suicidal thoughts but I don't know if this whole thing is me just overreacting or what. I've been sleeping more than I should even though I know the night before I got 12 hours of sleep. I don't want to go to the doctor and have them tell me that nothing is wrong when I know there is, and no one else believes me. Please, I need someone's help

You guys are being very helpful, but, I have another question. Is depression or Bipolar disorder hereditary?
There is a history of both in my family, and that would really help to know.

Definitely start with a counselor! They can stear you in the right directions.

Nutrition and EXERCISE can help a lot with mood!

Learning the ability to self reflect------why am I feeling cranky right now--------will help you deal with your moods as well and you can learn this in therapy.

Suicidal thoughts are serious so please get into some therapy!!!!! Antsy feelings, restlessness, sleeping too much, too little can be signs of a mood disorder-------so you are at least intelligent enough to know something is wrong. Follow those good instincts!!! They will help you out in life.

this clip talks about bipolar disorder.from what you describe i think you have it.talk to the psychologist about your problem.they'll know if you really have bipolar or not.

go to a therapist or psychologist they will know something is wrong and they can help u

If your doctor tells you there is nothing wrong w/ you, go to another doctor. Keep going until you find one who believes you and don't give up. In this day and age, most doctors should be keenly aware of just how prevalant these disorders are, especially in teens. You will find help. Tell your mom, she will be your biggest ally, trust me. I would suffer anything myself if it would take away suffering from one of my kids. Trust her and reach out. Good Luck.

**Edit** It is hereditary. If you have it in your family, it doesn't mean your destined to get it, but your chances are increased.

I am a bipolar, and the way you get labeled with this is if you have at least one manic episode. It does not sound like you have reached that stage. You want to avoid this since it breaks something in your brain which makes recurrence inevitable, unless you take lifelong drugs.

Doctors are drug pushers so if you go to one you are bound to come away with a prescription for something, not necessarily good for you.

What I'd suggest is to go to a nutrionist to analyze your diet and to see what minerals and other stuff you are lacking, amino acids, essential fatty acids, etc. That might well take care of your mood swings.

Take care of yourself.

I also have BiPolar or as I like to say Manic Depressive. I understand how you may have felt in the car. I will get extremely excited and have an anxiety attack if caught in a traffic jam or when riding with someone else. I can't stand to drive behind a big vehicle that I can't see around as I feel trapped in all of the above situations and that causes my anxiety attacks.
Your best bet is to see a doctor in the field of psychiatric medician and theorpy. You can call the local mental health authority in your county and they will tell you what steps you need to take. There are many clinics that will see you on a sliding scale fee and do not prescribe mind altering or addicting narcotics. They treat you with theopy and medications that do not prescribe things such as narcotics or benzodizopam.
I am usally manic or extremely hyper most of the time and then "crash" for a few days or a week every month or so. I am the opposite of what most people know as bipolar. Most people with bipolar are usually depressed most of the time and every now and then have a period of "up" time.
I have times where I get extremely irritaited over nothing. If my housecoat gets caught on the cabnet doors a couple of times, I want to snatch the doors clean off the hinges.
There are days I can't even stand to look at my husband or watch him chew his food and then all of a sudden as quick as those type feelings start they stop. It is a roller coaster ride but just hold on and you can make it. It is not a hopeless situation. You may not even need medication but theapy. Sometimes just knowing what is going on with yourself makes it much easier to deal with it and make it through. I can understand the feelings you are having if they are indeed caused from bipolar disorder but things are not hopeless, just a bit more difficult but you can live a great life with the illness.
