pregnant with panic disorder

a few months ago i decided to stop taking daily meds to try and manage my anxiety and panic disorder with coping skills and grounding techniques. it’s not going very well and i just found out im (happily) 6 weeks pregnant. my heart rate has been much higher the last few weeks of course which i’ve read is very normal for pregnancy but how do i learn that it’s not panic. i am having a hard time accepting that a high HR doesn’t always mean anxiety. can anyone else relate? i also have serious insomnia for the first time ever so im already not sleeping well.
