This is what I do when I am attacked. Works every time.
The fact that you feel like you're being attacked by Satan is good sign, actually. It means you're doing RIGHT and you're getting stronger in the Lord and Satan HATES that! So he's going to do everything he can to stop you.
Take encouragement in that. And let it make you stronger. Don't let Satan get a foothold.
As a Christian, you are given authority over Satan in the name and in the blood of Jesus Christ. Whenever you feel an attack, rebuke him in Jesus' name, telling him Scripture. Even screaming at him is sometimes a must. You are the head and not the tail. Bind him to hell where he belongs in Jesus' name. People can pray for you, but when it comes to the Spiritual realm, sometimes it just doesn't work unless you do it yourself. Some people refuse to do so, or believe they can, and Satan eats at their strength, feeding on their cowardice.
There's a study you can look up on the power of Jesus' blood. He shed His blood to heal you. You don't have to take these attacks from the devil. Pray the blood of Jesus over you that heals you. Claim the victory you have in Christ. You can find the study here:

This all is what I call battle praying. It HAS to be done with words. I don't know if you pray outloud or to yourself, but this one HAS to be done outload. Satan cannot hear you defeat him in your head. He can feed things into your mind, but he does not know what you think. He knows you for your actions.
I pray blessings for Melleah, and that she is able to overcome these attacks through the boldness she has in Christ. I pray for her protection and boldness and peace and trust in You who we know is in complete control. I pray the blood of Jesus to cover her and heal her and transform her. I rebuke these anxiety attacks of the devil in the name of Jesus Christ and I bind Satan to hell where he belongs. And I pray that the Holy Spirit within her would shine so bright that it rids of all darkness that tries to touch her. Amen
