Sorry I took so long to get back to you, I have been a bit busy at work.
I think the main thing to think about, is that you want your life to change. By chanting you are changing your thoughts and your mind.
Bad things happen to people in life all the time, it doesn't necessarily have anything to with chanting.
But if you study and read more about Buddhism, it will teach you that the struggles in life are there to help has become stronger and grow as people.
We can't escape them. They are part of life. Dark and light. Night and Day. Winter and Summer.
We chant and practice Buddhism not to escape from suffering, but to have the strength and courage and wisdom to deal with anything that life throws at us.
Chanting is changing what is in your mind, it then changes your thoughts, then your life, then your friends, family, community, country, world etc
We are all connected.
This practice is about everyday life, about happiness and being the best as a human being.
This is about human revolution.
Hope that makes sense.
