I think you should (and have every right to) expect more than that. Mental health should not be taken lightly and should never be ignored. They should have called you if they said they were going to. To be honest, if this is a GP then I've never found them much cop with mental health. They're a general practitioner, so don't specialise in mental health. They're not the best for accurate diagnosis. To expect you to take medication without explanation or even instructions as to when and how to take them is utterly ridiculous and irresponsible. But I have found GPs tend to throw pills your way and leave it there because that's the easiest thing to do. You get the odd one or two who are very helpful and knowledgable, but I've found them few and far between. The GP I usually see is a nice guy, he listens, takes me seriously and isn't awkward about prescribing things to help with anxiety. But, there is a limit to what he can do for me, and even he himself has admitted that even psychiatrists aren't that great here. To me, every psychiatrist I've seen has just written a prescription without listening to me and making a nice wage for the privilege.
Personally, I think you'd be better off telling your doctor you want to see a therapist because they'd likely be far more helpful to you in the long run. They spend time with you, regularly, getting to know you. And if you build enough trust with them, they could really get to the bottom of your problems and that is the best thing you can do because if you don't know what it is, or why, then it's harder to treat. Sometimes you don't even know what's bothering you the most. I've heard many say its better to treat the most bothersome symptom, which is obviously going to help, but you need to try to get to the bottom of why instead of burying it under an endless course of pills.
Saying this, I'm assuming you're unsure of what specifically you're suffering from. I do apologise if I'm wrong.
