I think Im bipolar,, advice?

I dont really know how these forums work but hi, I'm a 17 year old girl in public highschool and i think im bipolar. i dont know for sure though and i dont want to go to my parents with this and cause them all this stress and have it turn out to be nothing, especially right now because they are having trouble with a younger sibling of mine who is having health problems that nobody can really figure out right now. The thing is everything in my life is going pretty normal, nothing to bad and everything pretty average/good. But all the time i have days where i feel great, like super happy feeling healthy ready to take on anything and sometimes it turns into me just being insane hyper and laughing constantly and acting off the walls. But then there are other times that last for anything from a few hours to a week or so when i feel absolutely lower than low. i just feel like being alone and away from everyone, also i normally fell pretty exhausted during these bouts and i skip school alot bc i dont want to have to put up a front for anyone. but then it ends and i feel absolutely one hundred percent normal, so i just hush away the thoughts that maybe im not absolutely one hundred percent normal.
so what do you think? am i just blaming teenage hormone fueled mood swings on a disorder? what did you feel like before you were diagnosed? how old were you? really im just looking for advice/someone to talk to. My close friends that ive tried talking to about this just blew me off and said it was nothing but i feel like this cant be just nothing.
oh and please excuse my horrible grammar/punctuation.
thanks for any feedback.

Hey,

When I tried to talk to my friends about my own problems at around your age, they also ignored what I said. People just don't want to know about these types of things, unfortunately. I would hold-off telling your parents too, unless it becomes so serious that you actually cannot function in life. My fear is that they would point-blank reject it to (i.e. your problem) and it could make you feel worse actually.

Whether it is hormone-related or not is only slightly important... The fact remains that the problem seems to come and go in a cycle, just like Bipolar. How long has it been going on for (if you can remember)? For now, I would try to read other threads here to maybe lean more about what others are feeling/going through too. Also, read websites (ones that look reputable and that don't form opinions/biases).

In the future, hold off from talking to your friends about this because they might never accept it. Try to get from them what you can, which is a fun time and love/affection. I know that you'd ideally like to talk about the problem with them, but they just mightn't understand it...

Take care
Kevin

Talk to your medical doctor. Keep a diary of your symptoms or recreate one going back as far as you can to see if your symptoms coincide with your period, events, stress or other cycles. Have him do a complete physical checking your thyroid, hormones,do blood work looking at anemia, B-12 and vitamin D levels. Once you get the results, ask him if he thinks you should be seen by a psychologist or psychiatrist.

Try to consult with your doctor. He/she will first try to determine what may have triggered the mood episode, and identify any medical or emotional problems that might interfere with or complicate treatment.
