I noticed since a few days ago, that when i'm about to sleep, like just as soon i start falling asleep.. my heart starts racing and i have an urgent sudden need to go up and take a deep breath, as i was running out of air. I i know for a fact that this is anxiety since i was recently diagnosed with it. 

But this is really annoying cause i have to wait and breath slowly and for minutes to calm down and try to sleep only for it to happen again... and basically it does that 3, 4 times until my fatigue gets the best of me and my brain gives up. And that makes me always sleep deprived...

Anyone have a trick to avoid this ?
