Citalopram
"From the age of 19 to now 35 I have been off and on anti-depressants   Finding a good Doctor and Citalopram has changed my life. The last 5 years I have regularly took 40mg a day.  I have been able to function and live a normal life. I am half way through a masters Degree in science and doing well. I may have been there sooner with the right treatment.  I read lots of negatives about this drug, I can only say if it doesn't work for you then its not the right medicine but don't let that stop you talking to a professional. For someone who has lived with depression as a teenager, just know that there is hope and life can get better. From the lowest of lows and dark places."
