Here are my thoughts: if Dan is anxious right now regarding current stressors (job/family/money issues), medication may not be a bad idea short term to help him cope with those things while continuing to function. If he's always anxious, it's definitely good to figure out what's going on there and perhaps think about a long-term strategy.
My OB put me on 50mg zoloft after my second miscarriage because I couldn't function. He basically diagnosed me with postpartum depression. I asked to be referred to a psychiatrist/therapist anyway, and the psychiatrist ended up agreeing with my OB about the medication and dosage, but she did order some basic lab studies (thyroid panel, liver enzymes I think, vitamin D and vitamin B12 levels) as well. She diagnosed me with an "adjustment disorder", basically meaning I wasn't coping well. Then she referred me to a therapist. I told her I was hesitant about meds, and DH was especially hesitant because he felt like they were just putting a bandaid on the issue.
The psychiatrist told me she was recommending the meds for me in order to act as a "floor" for me. I still had to deal with the stress and grief and anxiety, but at least I had something to keep me afloat in the meantime. It's been tremendously helpful for me in terms of keeping me from getting REALLY upset about certain things, especially when I'm at work and have to be on my A game at all times. I've also been in therapy since that time, which has also been very helpful.
Anyway, the moral of that story is that I don't think the meds are necessarily a bad idea to help Dan stabilize himself while dealing with whatever is making him anxious. But I do agree that seeing a psychiatrist to confirm that the medication and dosage are appropriate and see if therapy is appropriate in combination with, or instead of, medication.
