As i get older I slowly realise more and more just how the world is and how it works, and the feelings of depression and helplessness grows.

Age has nothing to do with experience. I don't know what your experiences are so I can't comment. All I can say is, if you are feeling helpless, there's always a skill that could be developed to remove that sense of helplessness and with that the associated depression goes away. When you see yourself contributing positively towards things no matter what they are, depression would slowly go away.
