Why Am I Angry God?

Hello God it’s me Cyndi. God, I’m having trouble with the people you are sending to me. I’m having trouble with relationships. How do I know if they are in my life for a reason, for just a short time, or for a lifetime, I wish I had a little light that would go off to tell me if I should even waste my time. How do I know that someone entering my life is not going to hurt me? How do I trust people God? How do I stop making unrealistic expectations? How do I make that go away? How do I stop expecting a emotional response or reaction from someone that is incapable of giving it to me.? And why do I assume that everyone knows what I expect? They are not mind readers. All it does is cause myself anger and disappointment. How do I stop expecting something so I won’t then get angry. Please God help me understand how to just trust you. To trust you to send me what I need in my life and that even if I’m hurt, the hurt will go away and a lesson will be learned.
