i dont blame ya, its getting wild.
essentially just talk to your doctor, tell him how you feel, ask for anti depressants just ask, and he might either give you them or he'll ask you to fill out a survey.
I reckon their handing them out like candy atm. With the survey it'll just be a quick questionnaire to reckon how fucked in the head you are
From their he can decide to prescribe or whatever, you'll have two awful weeks during the "initial" period of taking them, after that its just plain sailing
