Faith;

It is the Lord who goes before you. He will be with you;

he will not fail you, or forsake you. Do not fear or be dismayed.

Deuteronomy 31:8

When i called, you answered me; you made me bold and stouthearted.

Psalm 138:3

For God did not give us a spirtit of timidity, but a spirit of power, of love and self-discipline.

2 Timothy 1:7

My presence will go with you, and i will give you rest.

Exodus 33:14

The joy of the Lord is your strength, lean onto him and he will guide you, ask him for guidence and his hand and he will reach out to you, as you reach out to him. He will walk with you in life, even when your strength is gone, just hold on' He will reach out to you and hold you in his hands.

Dont do it on your own, and dont dwell on the past. Dont lose your faith when your strength is out of reach, reach out to him for he will always be by your side, he wont ever let you fall.
