A therapist or counselor may be able to issue a doctor's note for depression. It ultimately depends on the specific requirements of the organization or institution requesting the note. Sometimes, the organization may require a note from a licensed psychiatrist or medical doctor. However, a note from a licensed therapist or counselor may be sufficient in other situations.   It's important to note that while therapists and counselors can provide mental health treatment and support, they cannot prescribe medication like psychiatrists can. So if medication is a necessary component of your treatment plan, you may need to consult with a psychiatrist or medical doctor in addition to your therapist or counselor.
