Panic disorder?

A friend recently confided that they have been feeling frustrated, and after hearing their story, I thought it might be a panic disorder.

I haven't been able to talk to him yet.

I think it would be better to sleep a little more and then talk.

That friend seems to be like a tunnel, unable to pass through, often returning back, unable to travel by plane, so they only travel by car, and sometimes they experience symptoms like chest tightness or rapid heartbeat.

I think it's appropriate, so I plan to recommend a hospital consultation soon.
