Stay close to God. His promise is to renew your youth.

Psalm 103:

Bless the Lord, O my soul;
And all that is within me, bless His holy name!
2 Bless the Lord, O my soul,
And forget not all His benefits:
3 Who forgives all your iniquities,
Who heals all your diseases,
4 Who redeems your life from destruction,
Who crowns you with lovingkindness and tender mercies,
5 Who satisfies your mouth with good things,
So that your youth is renewed like the eagle’s.

Never forget God.  There is great hope in Him. Seek Him as much as possible! Follow Him!

Proverbs 3:

My child, never forget the things I have taught you.
Store my commands in your heart.
2 If you do this, you will live many years,
and your life will be satisfying.
3 Never let loyalty and kindness leave you!
Tie them around your neck as a reminder.
Write them deep within your heart.
4 Then you will find favor with both God and people,
and you will earn a good reputation.
5 Trust in the Lord with all your heart;
do not depend on your own understanding.
6 Seek his will in all you do,
and he will show you which path to take.
