Pregnancy & mental health... I’m really struggling

Before I got pregnant I was in and out of an inpatient mental health facility for some months and then spent 7 months doing outpatient therapy Monday-Friday all day long. Once I finished that I found out I was pregnant 2 months later. I was obviously concerned because of all of the medication I was taking and because of the amount of time it took to figure out the right combination of meds but didn’t know how it would work with my pregnancy. I saw my psychiatrist when I was 10 weeks along and we eliminated a few things that would not be safe to continue taking and got it down to a few that were okay for me to remain on. I’m 29 weeks pregnant now and the last few weeks I have felt myself really struggling. My depression, anxiety and bipolar disorder do not feel like they are under control and I feel like I’m in such a bad place. I called my psychiatrists office and the soonest they could get me in to see my doctor isn’t until January which is when my baby is due... I explained the situation to them and she offered no help. I literally do not know what to do. I feel so hopeless and defeated. I am scared because I know the thoughts, feelings and behavior I am capable of when my mental health isn’t being taken care of and I don’t want it to get to that point. I just don’t know what to do or where to go from here. 😞
