Thank you for writing in to Just Answer.
I'm sorry to hear what you are going through.
The Diagnostic Statistical Manual (DSM) is what is followed in the US to evaluate whether a person has a certain mental health disorder. You can look up the DSM criteria for the different types of Bipolar Disorder here
and see if it resonates with you.
However, self-diagnosis is not really advisable or effective. In order to best determine whether you have bipolar it is best to schedule a psychiatric evaluation with a psychiatrist. The thorough assessment will carefully evaluate if you have any mental health disorders including bipolar.
That apart,from what you describe, it sounds like you currently have a lot of stressors in your life - the responsibility of looking after two small children, a stressful job, conflicts with your husband etc. which could be leading up to anxiety
, irritability, and even a certain degree of depression. In order to best address this, you could consider therapy, if you are currently now in therapy. Working with a therapist will help you to learn different, more effective coping skills and strategies to address situations, and also help you get in touch with, and process your day to day feelings of stress, anger etc.
I hope this is helpful.
Please let me know if you have any clarifying questions/thoughts.
