Do adrenaline dumps always give you a high heartrate?

I've been freaking out today (hr was in the 110s and 120s while laying down, usually in the 70-80 range), suddenly after a while of being anxious I managed to calm myself down, but my heartrate was still high

ive been resting since, and now my hr is 80. i got up to use the bathroom and felt better than i usually do.

I'm really worried these are signs of an adrenaline dump. I'm not pushing or using this energy, but if I crash tomorrow that would be really bad. Has anyone experienced this and had it not mean a crash is coming? anxiety and then calm and feeling generally better than usual?

again, regardless i am not pushing i promise. i just hope the normal hr might mean its not adrenaline
