There is one thing you should know about writing. It will will inevitably lead you to terrible places, as you cannot write about something if you have not lived it. Through the most important thing to bear in mind is this: you are there as a tourist and must always remain one.
There was a very specific reason why you were blessed with the ability to translate your sentiments into words- it is to bring a voice to suffering and torment. But, do not be too indulgent with your expericance of these things- despite how addictive suffering can be- how easy it is to get lost down that twisted path of self destruction. You must emerge from adversity , scathed but victorious- to tell your story and in turn , light the way for others.
