Bipolar disorder might be a possibility, but you would only know that after having an evaluation from a mental health professional. He or she would be in the best position to determine if you have bipolar disorder or any disorder.
Since you’re worried about hyperthyroidism, it would be advantageous to undergo a medical evaluation. Your primary care physician could provide a referral to a specialist. It’s wise to investigate every possibility.
I’m also wondering if you are taking any medications. Some of the symptoms you have described could be side effects of medications. Medication can slightly alter our personalities. Sleep deprivation can also cause some of the symptoms you have described.
Consider keeping a journal to track your symptoms. You might uncover a pattern. That information will be helpful to a mental health professional attempting to determine what might be wrong.
More information and professional evaluations are necessary for a diagnosis. Your next steps should involve in-person evaluations with your primary care doctor and a mental health professional. Please take care.
