Even through a sea of tribulations the best you can do is to keep hope and fight for the peace you are looking for. God has given us the tools to be happy, but it is we who must know how to use them. Learn to use your strength and fight the negative energies.
A spirit plagued by evil feelings will never have peace. Whatever happens, keep in mind that much of the solution is within you and never lose hope.
You can do anything you want.
