Read His Word. He will comfort you and encourage you and speak to you through it. There is a scripture that says, "I will never leave you or forsake you". God is faithful and He keeps His word. If you feel discouraged or alone or depressed in any way...read the psalms
If someone you know wrote you a letter as to do something for them you will believe the letter is true Right Gods Word is a Love Letter to you to know the Truth, He said I will never leave you nor forsake you, Endless upon Endless Words of Love to you my friend to me and all who will come to Him in Faith His Word is Jesus Christ His Son, you can count on His Word as the only Truth in this very short life.
In order to feel like God is still with you, you need to find a way to connect with him. For me, the best way is by singing songs of hope, faith and praise. You have to find your own way of connecting. Prayer is a great way to connect and feel close to God. Some people need to pray out loud, to feel really connected. You just have to find out what works for you. Take care
