Many drugs can be prescribed by a gp here and you need a gp to refer you to a psychiatrist if you can't afford a therapist. Combinations are rarely prescribed (because they like to rip us off and deny us the treatment we're paying for because f**k us that's why, ain't that lousy?) but sometimes a gp would get you started with antidepressants and your psychiatrist could suggest additional meds after a thorough evaluation of your condition. A gp will often suggest you also join a support group but I've learned recently that those are not covered by insurance and you have to pay extra for meetings. Healthcare here can be really messy, confusing and very patient un-friendly, ugh.
