Want to see if anyone relates

Ive been diagnosed with anxiety since like 8 years ago and it’s pretty much always been there. It has been very bad but recently, I noticed a new development in it. I’ve always had sleep issues too and most nights I need melatonin to put me to sleep.

But recently, ive noticed that whenever I am wrapping up to go to sleep, my heart starts THUMPING and pounding before trying to fall asleep. Whenever i pick up my phone again tho, it goes away. I put the phone back down, boom its back. Even melatonin doesnt work sometimes.

And ill be honest, while i am going through a very very pivotal and stressful point of my life right now, I feel like Ive made peace with it mentally to a certain degree but maybe my body is still on fight or flight?

To add, I go the gym, eat quite healthy, take my supplements, etc. My GPs have been quite unhelpful.

I am wondering if anyone has every experienced anything like this?
