If you're on meds for such, another visit to your medical practitioner to discuss increase or decease may be required?
In my own circumstances and over a life time I've created some habitual responses to stress and anxiety which produce the physical symptoms you mention in addition to others.
Breathing is playing a major role in changing the outcome for me but first,
I found I wanted to understand what was happening to me. Cause and effect if you like.
When I repeatedly think this or that,
I trigger or inhibit a chain reaction within my own body to produce said physical symptoms.
On changing what I think,
Or at the very least, pausing (and breathing) before reacting,
I can change the chemical reaction happening inside my own body and thus the physical outcome...
Albeit slightly, but I'll take slightly over no change,
means it's beginning to work
By 'breathing' I mean exhaling for longer than inhaling.
For example inhale to the slow count of four, exhale to the count of eight.
I'm not cured by any means. I find I can function a little better in situations where previously I couldn't.
It's progress
