Trusting does not mean you never experience life's valleys. There will be peaks and valleys as long as you live on this physical plane. There is no happiness without the opposite experience of unhappiness. Opposites are the way it is in the physical plane. Expect that this is also your reality.
Do not abandon trust when your ego thinks things should be different than they are. It is better to embrace trust when darkness is present, knowing that light will follow. Begin to look for the lesson in the darkness rather than cursing it. Trust allows you simply to observe the dark and unhappy times rather than identifying totally with those aspects of life. From this perspective you are not at the mercy of your ego energy, insisting that everything must be perfect, and that when things are not, you have reasons to give up your trust in the divine.
The valleys are merely the way of the physical plane, but they are not who you are. You are part of the unseen wisdom that created this entire physical plane and you can trust in it uncategorically.
