Hi, Valerie, there's nothing wrong doubting your faith, it's quite normal. First, ask Jesus to make Himself more real to you, to increase your faith. Faith is a gift of The Spirit, and God will give you more, if you ask Him to
.
Also, you can ask God to fill you with The Holy Spirit (Jesus called Him "The Comforter"), because He will strengthen your walk. Luke 11: 11-13 Is a good passage to read........."How much more shall your Heavenly Father give The Holy Spirit to them that ask Him?"............
God bless.
