What is this?

Anxiety, oppression, worry, fear, doubt...what is this? More importantly, what does God have to say about these life crippling diseases? I am beyond exhaustion living in this constant worry that I am making too many mistakes, not following God closely enough. Letting him down, letting the people down around me, letting myself down. Enough is enough--I am getting to the bottom of it. What does God have to say about these feelings that have drowned out my joy in life. Typing in "anxiety" into the Biblegateway.com search engine... 1 Peter 5:7 Give all your worries and cares to God, for he cares about you. "worry" Matthew 6:25-34 “That is why I tell you not to worry about everyday life—whether you have enough food and drink, or enough clothes to wear. Isn’t life more than food, and your body more than clothing? Look at the birds. They don’t plant or harvest or store food in barns, for your heavenly Father feeds them. And aren’t you far more valuable to him than they are? Can all your worries add a single moment to your life? ... "oppression" Exodus 3:17 I have promised to rescue you from your oppression in Egypt. I will lead you to a land flowing with milk and honey—the land where the Canaanites, Hittites, Amorites, Perizzites, Hivites, and Jebusites now live.”’ Psalm 72:14 He will redeem them from oppression and violence, for their lives are precious to him. "fear" 1 John 4:18 Such love has no fear, because perfect love expels all fear. If we are afraid, it is for fear of punishment, and this shows that we have not fully experienced his perfect love. "doubt" Psalm 94:19 When doubts filled my mind, your comfort gave me renewed hope and cheer. Matthew 21:21 Then Jesus told them, “I tell you the truth, if you have faith and don’t doubt, you can do things like this and much more. You can even say to this mountain, ‘May you be lifted up and thrown into the sea,’ and it will happen. These are all promises from MY God. My covenant promise to my God is to serve Him to the best of my ability every day without giving up and this is what He promises me. What is a promise that the Word gives about Satan? John 10:10 New Living Translation (NLT) 10 The thief’s purpose is to steal and kill and destroy. My purpose is to give them a rich and satisfying life. OF COURSE I AM FLOODED WITH EVERY JOY STEALING, CRIPPLING THOUGHT-- The enemy wants me dead, he wants to steal every good thing that Jesus died on the cross to give me. And I am just sitting back and letting him?! Absolutely NOT! Lord, FORGIVE ME, for every time I have allowed the enemy to zap all the life and light out of me by believing his LIES. Lord I was made for battle, I was made to fight the good fight of faith for YOU and YOUR KINGDOM and YOUR PEOPLE. Lord, GIVE ME STRENGTH because my flesh is WEAK. I need you more than anything else for now and eternity. May you flood me this day with reminders of Your goodness and Your love and may I never falter in what you have for me. Your love endures forever. My love for You will endure forever. Renew my mind in You, I need you. In Jesus' Name, Amen.
