Cares are anxieties. Cast your care on God by giving over the control of the situation to God, let him manage the flow of circumstances, give him the right to manage your feelings and let it go by faith.
You can have good sense and organized procedure while also having God in control of things and honoring Him. You have to be willing to give up what you have to God for someone else’s needs, without thinking of yourself and what you’ll get back. Yield some portion of your life to God for Him to use and you’ll be blessed for it.
