Re-learning - There's no such thing as depression

If there was no such thing or knowledge of depression or self-consciousness what would I do?

I would continue to live my life not over-analyzing shit. I am still young. STILL. What can I do? What can I put my mind into? What what what what what what what? Am I focusing on pleasure, joy, or happiness? Am I focused on healing or serving? Am I too selfish and just focusing on myself?

I need to build myself to be the best so I can help others! Keep at it!
