The distinction is straightforward and consistently confused. Therapists — psychologists, LMFTs, LCSWs, LPCCs — provide therapy and don’t prescribe. Psychiatrists are physicians who prescribe, and some also provide therapy. Psychiatric nurse practitioners prescribe and are considerably easier to access.
And your GP can prescribe for common presentations, which is the option people most often overlook.
Who actually needs a psychiatrist
Complex or treatment-resistant presentations. Two or three medications tried without success, or an unclear diagnostic picture.
Bipolar disorder, where getting it wrong matters — antidepressants alone can destabilise someone with bipolar disorder, and the diagnosis is frequently missed.
Psychosis, or any suspicion of it.
Multiple medications, where interactions need managing.
ADHD, in practice, because controlled substance prescribing makes many GPs unwilling — though some will continue a prescription once someone else has established the diagnosis.
Pregnancy and breastfeeding, where a perinatal psychiatrist is genuinely worth seeking.
When your GP is enough
For straightforward depression and anxiety, a first antidepressant from a primary care physician is entirely standard practice and is how a large share of these prescriptions are written everywhere.
It’s faster, far cheaper, and covered. The practical advice is to be specific in the appointment: say what the symptoms are, how long, what you’ve tried, and that you would like to discuss medication. And ask for follow-up in four to six weeks rather than leaving with a prescription and no plan.
Where a GP is less suitable: anything on the list above, and situations needing careful dose titration —OCD in particular requires higher doses and a longer trial than most GPs will be familiar with.
The Bay Area reality
Psychiatrists here are scarce, expensive, and frequently out of network. Private-pay initial evaluations commonly run several hundred dollars, follow-ups less, and waits of months are normal for the well-regarded ones.
Psychiatric nurse practitioners are the most useful thing on this page. They prescribe independently in California, are considerably easier to get an appointment with, and generally cost less. For routine medication management their outcomes aren’t the reason people avoid them; unfamiliarity is.
Telepsychiatry widens the pool to the whole state, and for medication management — which doesn’t require a physical examination — video works essentially as well as a room. More here.
The combination question
For most anxiety and depression, therapy plus medication outperforms either alone in the short term — and therapy’s gains hold better after treatment stops, while relapse on discontinuing medication alone is common.
The practical implication isn’t that one is superior. It’s that if you’re only going to do one thing and the presentation is moderate, therapy leaves you with something that survives.
