High Resting Heart Rate During BPD/Anxiety Episode

Lay down in a dim lit area... close your eyes and breath in 5 seconds... hold 2 seconds... breath out 5 seconds and repeat... that's what I do.... sometimes though it doesn't cut it...

I go to my bathroom and shut the door so it's dark and then use a sound app set to sound like water. 5 minutes later my stats are as close to "normal " as I ever am.
