I am a software engineer (US - 6 years at this company) who has been traveling a lot for work. Last business trip, in December, I had my first set of panic attacks mid-drive. I thought I was going to die and went to urgent care who recommended I seek treatment for GAD. I am in the process of scheduling an appointment with a PCP/Psychiatrist (waiting for a response to my appointment request). I had to cancel that business trip midway and came home for holiday break, so my manager is somewhat aware of the situation.

I am terrified of traveling again until I get medical treatment. I have a history of being easily stressed, but have always been able to manage it through breathing, positive self-talk, etc. Lately my anxiety suddenly spikes up for no reason, especially trying to sleep. Do I tell my manager I am seeking medical treatment and wish to refrain from traveling until then? There's probably a delay in appointments right now, so I'm worried about how inconvenient it would be for my coworkers. Thanks for reading.
