You used the word "feel" four times in your post, but it appears zero times in the fourth amendment:
> "The right of the people [1] to be secure in their persons, houses, papers, and effects, [2] against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
The clause labeled [2] limits the scope of the clause labeled [1]. It's not a free-floating right to "feel secure" against anything--people following you, etc. It's a right "to be secure in [your] person" "against" a specific intrusion: "unreasonable searches and seizures."
If it said: "you have a right not to be mauled by lions," that wouldn't mean you have a right not to be eaten by hippos. Much less that you have a right not to "feel" threatened by the prospect of being eaten by hippos.

It the word "feel" distracted you from the underlying point.
First: "being secure in your person" does mean to include feelings as well as actual harm (“protected from... danger” as well as "free from fear"). See [1] for example. I am approximately 99% sure the authors of that amendment would have felt that government officials following them around would have directly violated that amendment, and I would be shocked to hear you're actually arguing otherwise. (Are you?)
Second: you're either misunderstanding or completely ignoring the actual physical danger here. Again, I refer you to my previous question, which you did not address: if I was stalking you 24/7, would you say you ARE secure in your person/effects/etc.? If other people claimed you ARE secure, would you agree with them? Would it change if I was a police officer? Are you seriously going to argue that my stalking is only impacting your feelings regarding your security, not your actual security?
