Cast all your anxiety on Him for he cares for you. 1 Peter 5:7
Your situation may never change. Your children may never stop doing dangerous things. You are going to die someday. Everyone will. You can enjoy flying without gripping the arm rests. You may get sick, people do.
Please know when you worry you make yourself into an ineffective prayer warrior. Pray, trust, believe, then let it go. Your fretting and anguish will not bring you closer to God or change anything. Many worriers out there need to understand when you worry you make Satan very thrilled. Don't keep saying "I'm just a worrier" and go through life stressed and anxious. Learn to practice letting go of a situation knowing that by you worrying as it says in scripture in Matthew 6:27, "you can not add an hour to life."
Wake up each day and look at yourself in the mirror and say "I am not going to allow Satan to make me ineffective for you. I trust you God and will NOT worry" then walk away and let it go. If you have been a constant worrier as your daily routine this may take a while to get this new habit.
I have a son who flies planes for a living and another son and daughter in law who enjoy rock climbing. Do not wake up and fret all day. I am excited for them that they are doing what they enjoy.
Start your day and truly let God have your situation. Turn on some praise music and think of the song 'I Surrender All' then do just that.
PRAYER: You are always with me. You care for my needs and walk with me each day. I need your strength to trust you and stop trying to constantly be on edge. Help me Lord. In Jesus' name.Amen.
