Depressed/anxious need advice!

Hey guys so I just want to start off by saying I was diagnosed with anxiety and depression when I was a teen.. depression at 14 and then developed severe anxiety by 17. I saw a therapist and psychiatrist and tried out different meds until I found the right one for me, lexapro. I took lexapro until I was 20 yrs old.. I stopped taking it because I felt that at that point I wanted to try to manage my anxiety on my own.. which I found I was able to do until I got pregnant at 21. At about 5-6 weeks pregnant I developed hyperemisis which is just non stop puking all day.. more than 10 times a day.. I was so dehydrated and hospitalized multiple times, I lost 20 pounds.. and I felt miserable like why did this happen to me? But anyway.. being so sick and feeling like I could do nothing took a toll on me..I’m 30 weeks pregnant now I haven’t had an easy pregnancy and it’s my depression/ anxiety have made a comeback. I’ll have anxiety attacks where my heart is racing and I think I’m going to die.. quite often. And sometimes I’m scared to leave my house in fear that something will happen to me. I’ve expressed this to my OB and to a therapist in my OB office.. they suggested that I get back on my lexapro before I get even worse and they say that the pros outweigh any possible cons.. but I’m still scared. My OB sent me a prescription to my pharmacy but I’m scared to start taking this medication again in fear that it will have a major negative affect on my baby... but I’m also terrified of being unable to care for my child once she’s here because of severe anxiety. Could anyone please give me some advice or words of encouragement? Did you take anti depressants while pregnant? I’m just a ball of stress and worry now 😪
