You can try fighting clinical depression as much as you want, and might even succeed at it temporarily. However, if you do not have a firm goal or purpose to continue living, then it’s almost inevitable that you will succumb to the disorder again.
Drifting about in life without purpose is one of the most common causes of clinical depression. If you find yourself adrift, if you find yourself wondering why people around you seem to be able to find a purpose strong enough to motivate them every day, even if their purpose seems superficial to you, stop focusing on those negative thoughts and start focusing on setting a positive goal or purpose for yourself.
You might have reasons for viewing society, or life in general, differently than others. You might strongly believe you are right. Perhaps you encountered a rude awakening to “reality” from the perceived falsehood of your previous way of life or your thinking, and now feel completely disconnected from the community you once engaged with actively. However, resentment towards society at large can, without a doubt, lead to severe depressed emotions and feelings. Perhaps your purpose could be to awaken society to your different viewpoints. This will not happen easily, but again, having a goal to focus on is much better when trying to overcome depressive disorders without directly seeking help, rather than just wandering aimlessly.
