"There has no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that you are able; but will with the temptation also make a way to escape, that you may be able to bear it." (1 Corinthians 10:13 AKJV)
God will give you the victory. Pray and ask Him for the strength you need. God answers prayer.
