Im 12. How do I know if im depressed, bipolar, or insane?

im so sorry about all that. i think it kind of sounds like ur depressed(your headache, for example is a symptom of depression) and u have good reason 2 b depressed. Also, being bipolar is hereditary so its possible u got that form your mom, but theres a small chance u didnt. But seriously, u should tell someone about this.(i mean other than the yahoo users) its not right for a persons family to do that to them.
