Anxiety medication at Urgent Care?

Can an urgent care provider prescribe an antidepressant? I’m already on Wellbutrin XL but I need something for short term use. I have panic disorder and even though my medication works long term, sometimes things spark my anxiety and I have a borderline panic attack. In those moments, I need something to calm me down.

My normal doctor is working from home and I can’t message her through their portal. The office said I would just have to call and see if they could take me. I’m not sure I can wait that long with the level of anxiety I’m having.

If you have any tips on how to settle anxiety and calm yourself down, they would be very appreciated. It’s hard to get out of this headspace once you’re in it.
