Welcome omo28; a person diagnosed with Bipolar II doesn't experience full blown mania like a person with BP I. The "manic" episode for BP II is called hypomania and can share similar symptoms of mania, but tends not to last as long or be as severe. For me the hypomania has been pretty mild and mostly presents as me being highly driven. Anxiety can be a part of the depression and hypomania for me.
We all experience this illness differently. My mom is diagnosed as well and our symptoms are completely different. I think it's fine to question the diagnosis and perhaps a place to start would be to educate yourself on Bipolar. You may also want to track your mood I use this online one at
