There are good aspects of worry that remove it for me from any list of sins. Thank the Lord you would worry if your children were playing near a busy highway. That worry would cause you to take precautions. Unlike adultery, which has no positive moments, worry can be beneficial, so I do not see it related to pride
Thank you for sharing your insights, dear brother in Christ! I meant to narrowly define "worry" as a sin when we do it after we have cast our problem before God.
Surely being worried about a charging hungry bear is not a sin but a gift of God.
But if I entrust a specific concern before God, it is sin for me to then pick it up again as if I did not trust Him with it in the first place.
And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive [them], and ye shall have [them]. - Mark 11:22-24
And again,
And immediately Jesus stretched forth [his] hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt? - Matt 14:31
God's Name is I AM.
