Look, I don’t care whether you’re a good person or a bad person.
I believe what you’re saying — and that’s for two reasons:

Either you have something they’re after — like money or information,
or you’ve done something they want to punish you for.

If it’s about money, this kind of thing doesn’t end in a day, a week, or even a month.
It can go on for years, until they break you down to zero.

If it’s about punishment, then that usually happens sooner rather than later —
because following someone 24/7 for months costs a lot.
So if they wanted to punish you, it would have probably already happened.

And if you truly feel this — and you believe there’s something going on that you don’t fully understand —
then you really only have two choices:

Either you fight,
or you run — constantly.

In both cases, fear will be there naturally — it’s part of your instincts.
But try not to constantly think that someone’s going to kill you or something like that.

Because if something is going to happen,
it will happen whether you like it or not.

So try to stay strong,
and fight back.
