Jittery? Anxiety?

I suffer from anxiety and panic attacks in regular life occasionally. I am starting to feel anxious and jittery now that I'm 6 weeks pregnant. Nothing is wrong but my mind keeps trying to make issues out of nothing! I used to take Xanax if I was having issues. I know this is not super safe for pregnancy. So you guys have any suggestions for how to calm this? Is it just hormones? Am I going to feel like this for the next 34 weeks 😞 Thank you.
