@Blissfullyme: I see what you're saying, and I've also read that Seroquel is approved for use in treating bipolar depression. I see the logic in using it as a fast-acting med to treat a mixed episode, especially since it also helps with manic symptoms. And indeed it has made the situation more manageable for me. I also see bpcyclist's point that an anti-depressant may be needed if the Seroquel is not enough. Even though Seroquel helps a bit, it may turn out that it's not the ideal med.

Whether or not a higher dosage of Seroquel will benefit me more is a matter of trial and error I suppose. I do like the idea of first trying to up the dosage of Seroquel before seeing about adding an anti-depressant to the mix. As I said I'm hesitant to try new meds, and I feel like this way there's a lower chance of new side-effects. If that's not enough I will definitely consider trying Wellbutrin or another alternative. In part it also depends on how this covid-19 situation develops and how quickly I can go back to my therapy sessions. I am really missing those quite badly in this whole ordeal. I feel like if at least that part of life goes back to normal, I could get by with fewer meds.
