Beta blockers

Instead of refilling my Ativan my Dr prescribed me 20mg propranolol, I can feel it lower my HR, but my breathing feels shallow and I just had the biggest adrenaline dump. I’m so tired of feeling like I’m allergic to everything or having a health related issue, like a stroke, heart attack, asthma attack, embolism etc

I feel like 100mg of pristiq isn’t helping at all, I’ve been on it for 5 years
