Antidepressants are relatively safe and good for short or long term treatment of your mood. it takes a few weeks to notice changes. You can drive, work, just carry on with your life really. Anxiety meds are addictive and you should only take them for a very short period of time or on occasion (é.g. Before flying if you are scared of planes). You can feel anxiety meds working straight away. They can make you drowsy or sleepy.
