Struggling with Mental Health During Pregnancy

So I am almost 25 weeks pregnant and having a hard time. Before getting pregnant I was on a handful of meds that kind of helped. (Lithium, seroquel, perphenazine,hydroxyzine, propranolol, Zoloft prazosin,abilify) since I can’t be on my meds pregnant I am only on Zoloft. I feel hopeless, suicidal, and in a constant state of paranoia. I talk to my psychiatrist once a month, my therapist once a week, and my ob who is also my pcp once a month. I think I’m more scared of getting back on my meds after birth. What if my illness got worst and the meds don’t work like they did?
