Suggest Treatment For Major Depressive Disorder

Im diagnosed with major depressive disorder, and im wondering if there is something more or different going on. My mood is depressed but i have been staying up reading random things or learning intensely about sylvia plath. My energy is kind of up and i am talking for frequently to people at school but my mood is still down. Currently, i just feel very agitated and cannot sleep. I feel like i forgot to do something or i need to do something. I feel like something hasnt be resolved and i know that isnt true. My physciatrist said i could be on the bipolar spectrum, but ive never had a full manic episode. Im wondering if you have any ideas of whats going on and if it is serious enough that i should email my actual pychiatrist.
