those online tests are really stupid they can tell you that you have it when you dont at all... Being bipolar doesnt mean just going from happy to sad its really extreme shifts from depression to mania which last for at least a week each. Just being annoyed easily also doesnt mean your bipolar ... bipolar people go from a normal state to a depression where they can barely get out of bed to manic where they plan to dominate the world and stuff like that... really the only way you'll know is by going to a doctor and reading about other peoples experiences as much as you can...

  Many of your concerns can be part of bipolar but only a psychiatrist could provide a conclusive diagnosis. When a person experiences rapid cycling their moods can shift in a short time frame. Having difficulty relating to people and becoming easily emotionally stressed is common as well in bipolar. Online tests can be misleading. Its best to discuss these concerns with a psychiatrist. The most important thing is that what is occuring is affecting your life and they should be able to help you and treat this.
