Cast all your anxiety on him because he cares for you. (1 Peter 5:7 NIV)
You feel alone. No one cares. You have experienced loss of:
The devil wants you to believe that no one cares. No one will help you. It is every man/woman for him/her self. This is the devil doing what he does best, his usual chicanery. Nothing is farther from the truth.
The Most High God has His agents dispatched all around us. You just have to reach out and they will appear. God's unconditional love is available to all persons. You cannot sink too low or rise too high to escape His love. He gives it freely, no questions asked. Sometimes He responds through His Holy Spirit, at other times through angels and yet other times through other people.
So if you are feeling less than yourself, call on God. He will answer.
