The presence of God is AMAZING! You can feel it in so many different ways! Some ways I have had it is where I felt like my heart was about to fly out of my chest! Feeling God is the best feeling you will ever have.
God  is Love. He will always love you even when you feel unlovable. He will always be there for you. Even through all the hard times. The feelings of doubt , and temptation. Don't be scared of what might happen or what is happening now. All you have to know is that Jesus will ALWAYS be by your side.
Romans 5:5

Such hope never disappoints or deludes or shames us, for God’s love has been poured out in our hearts through the Holy Spirit Who has been given to us.

Before Jesus left, He talked about the Holy Spirit coming. He would be the Comforter, The Counselor,and the Helper. The Holy Spirit IS the Spirit of God.
