How to deal with depression during pregnancy?

The title is pretty self-explanatory, but here are a few details. I'm currently taking latuda due to my bipolar disorder and was previously on zoloft, but I am unable to take it anymore, as it causes me to vomit profusely, and I am unable to keep any food or drink down when taking it. The past couple of weeks my depression and irritability seems to have peaked. Every 2-3 days I feel like absolute shit and I've only identified a few triggers thus far, most of which have to do with criticisms from others, societal views and pressures, and self-judgement due to feeling like I shouldn't be having these feelings in the first place given all of the blessings I have in my life. I just want a solution to this, I'm tired of feeling like this every other day. I want to maintain a consistently good mood but I can't seem to. I'm starting to loathe myself more every day for being depressed and irritated all the time. Any suggestions? I don't even know at this point
