Has anything else in your life changed? Have you tried to understand what events/thoughts are specifically triggering your anxiety? I have suffered from debilitating anxiety for years and found mindfulness to be really helpful with respect to anxiety. If your anxiety continues you may want to look into Cognitive Behavioral Therapy (CBT), it works wonders for anxiety disorders.
When was the last time you took Vyvanse? Also, when was the last time you to Remeron and also Visteril? All three of those can contribute to anxiety, especially if you're still taking them. Not everybody reacts the same to medications, while something may work well for many people there will always be outliers who have the opposite response. I am that way with Visteril - it literally gets me more spun up than coke lol.
I would be very hesitant about using benzos as they may immediately help acute anxiety, they are not meant for long term use and don't facilitate learning how to deal with anxiety. They can ultimately make anxiety worse, and have several other negative effects aside from the huge addictive potential. I would recommend a script for Indural (propranolol) before anything from the benzodiazapine class. Indural works very well to stop the adrenaline reaction and it is not addictive.
