Have said that, some degree of angst about inadvertently become a target, despite my relative unremarkable public presence, is warranted. Consider the following...
On Facebook, I post a comment for my friends that says something like, "My kid walked an entire mile to the park and back all by himself, too! A good haul for a 10 year old!" The government comes and collects that semi-public posting. Some in the government may consider that abuse (there are cases where overzealous government officials have indeed made that determination). Guess what? If data collection and analytics are sufficient, I may well be referred to the local child protective services. While it's not the same as the directed anger of the United States government against Snowden, it would potentially cause irreparable harm to my family nonetheless. Technology has the potential to enable economies of scale in bringing unwarranted intrusions to the least of us. Connect that with an increasingly paternalistic government and even mere mortals like myself have real reason to be deeply concerned.
TL;DR Just because I'm paranoid doesn't mean they're not out to get me :-)

Maybe one day you cut off the wrong FBI agent on the way to work, or may be a friend of a friend knows someone with access to the government database.
There are countless ways, outside of a Edward Snowden, scenario where the information may harm you but would not raise to the level of a National Security Investigation
We know for a fact the agents have used the databases to keep tabs on Friends, Family, wives girlfriends,etc. Even for their own Amusement, looking and passing around intimate photos... After all these are just insignificant citizens, not a threat to anyone, so who cares if they pass around your dick pics right...
The fact that your are insignificant means they probably would not think twice about using their access to look up info on you, why is irrelevant.
Then there is the Ever Present data leak, look at OPM, at any point one of these databases can be compromised and your data simply uploaded to Paste Bin...
People that marginalize the risk of their personal data "because I am not a terrorist" are just as bad as the "I have nothing to fear so I have nothing to hide" people...
They do a disservice to everyone attempting to fight the government overreach... you sir are part of the problem.
Databases of Ruin my friend... Databases of Ruin
I am not concerned that the government has taken a special interest in me, specifically, and is using these techniques to manipulate or harm me, specifically.
It is the latter that starts to lean toward delusional thoughts. Some people, lik Edward Snowden or Glenn Greenwald, do have a reason to think that way. Most people do not.
And I make a difference between concern and anxiety/freaking out. I have an anxiety disorder that is triggered by specific things. Government doesn't trigger it, but if it did, I would agree with a therapist it is a problem that needs addressing. Panic attacks are debilitating.
All this is to say that the details matter, when it comes to diagnosing mental health.
