PMDD - what’s your experience

Hi, I have PMDD and I think im pregnant.
My pmdd can be so bad to the point of not wanting to be alive and severe panic attacks. I’ve been managing with medication and it has eased up. Now I’m scared it could be worse. I’m also terrified that if it goes away in the pregnancy that it could come back 10x worse than before.
What if it can’t be managed? There was a point in time I thought I was beyond help. I don’t want to be there again.
What’s your experience with pregnancy and pmdd? This will be my second pregnancy.
I also have severe anxiety around the morning sickness side of shit because it was so bad last time.
