Hopeful,
I am so sorry this is such a rough time for you currently.
It does sound like the changes/stress at work...along with the numerous switches in your Rx's have you in a temporary difficult place.
How long have you been on your current A/D?...and have you taken anything for BP before? Beta Blockers, prescribed often for hypertension can also prove helpful for some with anxiety managment...
...so I think that asking your P-doc to oversee the two issues and come up with a combo treatment for you is an excellent idea!
You will get past this place...and into one of good management with time and continued effort/
Keep us updated and let us know how your appointment goes tomorrow, okay?
S.C.
