You definitely want to talk to a doctor Cindi, as aren't you taking hormones, etc.? That's very important information for what they decide to give you. Same with any medications.
It's also worth keeping in mind having a psychiatrist (can proscribe drugs)
and psychologist (cannot) so they can play different but specific roles in your treatment. There are forms you can sign that they'll have that allows them to communicate about you. (Or not, if that's what you'd prefer.) If need be usually, or if they have a number of shared patients and are just doing a regular round up of sorts.
For a psychiatrist, ideally you want someone you can just tell them all the shit you're feeling, etc. in ten minutes or so along with some basic medical stuff, and then based on their reading of the situation they proscribe drugs and/or talk about other medical based things like diet or what have you. You see them less often, once a month to every couple of months or more depending on your situation.
Then for general talk therapy (and related) you have someone else you can talk to for hour sessions or whatever once a week or once a month, whatever you need. This can be PhD Psychologist or MSW. They may have their own suggestions on what to take which you can then share with the psychiatrist and also weigh with your own feelings. In effect you're creating a series of checks and balances on yourself and also them. They may also know little about the medical side and just be someone who click with for talking out your issues.
You can certainly get people who do both, and there is a convenience there, but I personally like the separation and checks and having two opinions, etc. Also I've read that it's a more effective model for some. (It also can be cheaper because psychiatrists tend to cost more per minute as they are in higher demand.)
How well they work and to what extent and how they work is basically a process of trial and error that never ends. You may get something working and then try to push it a little more or add something and screw up the balance.
For me personally, I also like to inform myself about the drugs separately, even just looking at wikipedia can take away some of the black box feelings regarding them.
Arguably one of the hardest parts is once you get to a certain level of success trying to track incremental progress from there. You know you don't want to compare to your lowest low but it's hard to conceptualize a 2% improvement over the last month or something to somebody. This is why humans need to come with stats pages.
