When you are afraid trust in the Lord, turn to Christ and trust him in new ways. Do you have a tendancy to trust in the Lord always except for the things which matter when you trust in yourself? Turn to the God who is with you, who cares, who will give you grace when you need it.
Fear is to do with matters of life and death and these can only be addressed by scripture. Fear is a matter of trust. Who is out there who is big enough to deal with this world which I can't manage?
Learn the skill of turning to Christ quickly when things are difficult.
