It would be a shame if your doctor gave you a diagnosis, prescribed some medication and then sent you home to work things out on your own.
The truth is unfortunately, that might be what will happen to many who seek help for depression the first time. It may not be until your symptoms persist and the meds don’t work that your doctor will suggest some sort of therapy for you.
Everyone can benefit from therapy, even if they aren’t depressed, but if you are depressed it would be another really useful tool in your get well kit.
The bottom line is that it is good to have someone to talk to. The popular term is ‘talk-therapy’. Talking to someone whose only job is to listen to you! What a luxury.
