I'm on 40mg of citalopram and pregabalin twice a day.

Things have been OK over the winter but yesterday as the weather turned warmer I found myself feeling very anxious and somewhat panicked. I could feel my wind pipe closing and I became short tempered with loved ones. I'm due to see the doctor soon and I'm somewhat embarrassed that I'm still feeling like this.

From a medication point of view, where do I go next?
