Hi there, when I went o mine about 2 months ago, I sat down and told my doctor "I have been feeling really upset but not knowing why, and been sleeping much more thanI normally do, and my hand started shaking." And then she started to lead the conversation. Be expect to be asked about if you drink, smoke or take any drugs. Then he/she would probably asked you abt when did it start and maybe a few other questions about what has been happening recently etc. And at some point in the apoointment, you would do a test to see how depressed you are, it's just a piece of paper with a few questions, pretty straight forward, I think it's a bit too straight forward in a way...
Normally the first line treatment would be counselling, and you could possibly do it at your doctor's or you woudl probably have a counselling team at your college anyway. My doctor asked me if I want any meds when I was mildly depressed, which I of cause refused... she then todl me to try the counselling and go bakc in a few weeks time to have another check up.
I then went back to her after 6 weeks, which should have been a bit earlier, but I kept forgetting, anyway. She asked me how am I, and I just said "Bad, I cant handle it anymore." Then I gave her a list of symptoms I have been having (which I found quite useful, coz then it woudl ensure your doctor knows all your symptoms). Then we did the same test again... and bingo, I mear hit the top mark (the higher the mark, the more depresed you are.) (sorry, I think my pill is making me feeling high...). So then she gave me some AD, which again I refused, but she said I have to, and then she told me to take time off work/uni, and gave me 2 weeks off. I now have to go bakc to her in 2 weeks time to adjust the meds and she said if I don't feel any better, then she would give me some more time off.
So if your doctor think you are depressed enough, they would give you AD anyway, butI would never ask for it, coz it is not fun at all, mine one at he monment makes me feel extermely high and low, and I cant sleep... so if you are not really depressed, don't start the meds. About the statement, if yuor doctor doesn't intent to give you one, then just be honest and ask for it, explain to him/her your situration, simple...
Anyway, good luck with it and let us know how you get on.
