There are two facts you can take absolute comfort in. Fact number one, you are never alone. God is always with you, and if you are a child of God, He is inside you experiencing these feelings first hand. He is always there. And fact number two, He understands completely. Jesus Christ humbled Himself by coming to earth and putting on this flesh suit so that he could experience being in the flesh first hand. Why? So that we could have a High Priest who not only had sympathy for us, BUT even deeper, He has something even more powerful - empathy. He literally strapped on our earthly shoes and walked a mile in them. He knows what we are going through. He knows what emotional pain feels like. He didn't have to do that, but he did...because He loves us and desired to understand us with actual empathy.
