Severe anxiety during pregnancy

So, I have beeb to the ER countless nights due to severe panic attacks. This started around 20w. Now 21w.

I fr keot thinking I have something seriously wrong w my heart bc they found a murmur w a click. Some drs heard the click, some didnt. Got to see a cardiologist n I get my echo results tmr, also my holter monitor results. My echo tech told me I had nothing to worry about, but thats all she could tell me haha. My cardiologist heard the click but barely, said its mostly a benign murmur but wanted to check n rule out aortic stenosis and mitral valve.

Went to the ER this evening bc I thought I was having a heart attack. My chest was clenching, my shoulders hurt, my left arm went numb, my feet n hands were drenched in cold sweats. They had me hooked up to a heart monitor so they could see my palpitations, did an ekg for the 100th time n blood work. Ekg was normal, heart palpitations are harmless, and blood work was good, except potassium. My blood pressure was low tho 99/58, 94/66, and 97/50

They have set me up w a therapist, im glad theyre so patient w me bc even tho yes im pregnant n having panic attacks someone else needs more help then I do. I feel so embarrassed going in every night, so im thankful they gave me resources. Anyone else have severe anxiety n depression while pregnant? I have trouble sleeping, concentrating, constantly thinking im dying :/ no fun at all!
