If you’re certain you avoided 2 kidnapping attempts, can you get access to nearby security camera footage as evidence?
Spending 5 months following you without overtly trying to extort you doesn’t sound typical for a criminal gang. Not impossible, given the sums involved, but patience and caution aren’t their hallmarks.
Consider whether you are in the common age range for schizophrenia to manifest. Attempt to prove or disprove, with hard evidence that a 3rd party would believe, whether there really are external forces conspiring against you.
I would be asking myself which is more likely: that a criminal gang has been trying and failing to kidnap me for months, or that I currently cannot trust my perceptions.
I am not a doctor, lawyer, nor law enforcement officer and this is not medical, legal, nor personal safety advice.
