There are various causes for depression, and different levels and durations of depressive episodes. Some individuals may experience brief depressive episodes after a particularly triggering event (like the death of a loved one) while others may struggle with depression for years, due to more deeply rooted psychological or biological/physiological causes. Some important tools for managing depression include regular physical activity, relaxation techniques (like mediation), a healthy diet, a regular sleep schedule, and (of course) counselling. While these methods can be effective on their own, many individuals will benefit more from methods of depression management that combine these tools with medication. Some individuals may need medication as a sort of intervention to bring their mood up to a stable level where they will be able to engage in the use of these other tools, while some individuals - due to their biological makeup - will need to be medicated over a longer term.
There is nothing wrong with requiring anti-depressants in order to ensure your mental health. A lot of people who struggle with depression make it their goal to get 'off the meds' and manage their depression 'on their own', which is understandable. However, this will not be a possibility for every person with depression; because as already mentioned the disorder comes from a variety of causes, including biological, for which medication could be indefinitely necessary. If a person requires medication indefinitely to correct problems with their brain chemistry and to ensure that their mood is stable, there is no shame in that.
