What a tragic story, @ubani1. We can see how a person can slip into terrible habits, whether to escape reality or to ease pain. You have some powerful imagery and great lines, like this one:

The world and people around me fade into shades of grey and disappear and melt away like smoke into nothingness, leaving only me and the worries that fill me up like water in a glass.

There really is no escape from the things we must face in life!
