I don't know how the system works in the US (am UK) but one thing which is universal is that you'rr taking the bravest step in admitting that you're not feeling right. So a huge "whoop whoop" to you, my lovely!!
Just tell him/her how you feel, if you are crying frequently, sleep patterns changing, eating patterns changing, etc... all factors which are causing you concern; he'll set you on the right path to getting better. You're making that first, hugely courageous step; WELL DONE!! xx

I dont know hun. Ive had good and bad experiences with doctors. The last one I went to gave me a questionaire to fill out and he totalled the level of my depression and anxiety and decided I should try a different med!! Strange way to diagnose someone but there you go lol. Some Dr's are better than others, unfortunatly they arent psychologists or counsellors so can be a little cold. But ive had good experiences too and they asked me how I was feeling etc.. I cant remember the details of what he said though im sorry!

My family doc originally diagnosed me as depressed. Turns out I am schizoaffective with bipolar. I would see a phyciatrist. They will do this long evaluation. It is a ton of questions. Took me an hour and a half. Thankfully the nurse typed in all the answers I just answered yes or no to each question she asked me. They will ask if you sleep alot, have your eatting habits changed, do you have periods of hyperactiveity, do you hear voices, do you see things others don't see, are you afraid of people. I hope you get the idea. It is real simple just long.

You need to see a Dr and he/she will ask how you're feeling, eating sleeping, coping with life in general. Then you will be prescibed meds and maybe you will be referred to a psychologist or counsellor depending on your needs. You're doing the right thing in seeking help and is a good step forward. Good luck.
