If I were you, I'd go to the doctor and get an "anxiety evaluation" I did last Thursday. I'm now on some medication to treat me for anxiety and OCD. I'm not saying you sound like have OCD though, cuz I just think you may very likely suffer from Paranoia which an SSRI anxiety medication might help. But before you just go to doctor and ask to be put on medication for anxiety or Paranoia, get an anxiety evaluation.
As a counselor (not licensed yet, so don't take this as professional advice!), any personality disorder is much more severe than our GAD. And, oftentimes, people with personality disorders do not necessarily recognize that they have a disordered way of thinking at all. So..the very fact that you question yourself probably means that you do not have this. Also...NEVER try to self-diagnose. You can't be objective, so you should leave this to a professional. With that said, I can assure that you GAD can make you have all kinds of worries that "normal people" would not. Here are some of mine...if it makes you feel better: I'm terrified that people I love are going to leave someday and just disappear. I willl even get worked up if my hubby is in a store too long, because i'm afraid I will go in there to find him and he won't be there. I'm also afraid that I'm going crazy sometimes. Another one, I'm afraid that my heart will beat too fast and it might explode. Then there is the classic fear that a snake is going to crawl in my bed at night...even though I live in a two story apartment in the middle of a city. So..see...we all have those thoughts. No, they are not fun. But, we have them just the same, and we just have to learn how to let our rational minds overcome them enough so that we can function everyday.
Also, probably what's most important is that in my line of work, I have YET to meet an actual "NORMAL" person. I've heard they exist out there, but they haven't crossed my path yet! HAHA Every single person I meet has something...some kind of quirk...some kind of flaw...something. I guess that is what makes us all unique.
I don't know if any of this helps, but rest assured...you are not alone :)
Don't get hung up on these definitions -- they're just for insurance purposes or for pharmaceutical companies to get patents. Anxiety is anxiety, obsessive thinking is common to all mental dysfunction, it's just what we obsess about that is different. You're not hallucinating from your description, you're just obsessing. Not that I know how to fix it, or I wouldn't be on this board. Also, sometimes we make decisions, but when you are obsessive, the decision is never made. I wouldn't turn in anyone for selling weed because I think it should be legal, but I would pick up the wallet and turn it in to the police or look for a phone number to call the person to come get it. I would turn anyone who committed an act of violence, but being anxious like you, I probably would be afraid. But so are people who don't suffer anxiety diseases, which is why most people don't turn people in for anything. You know, just do what the rest of us do, get into therapy, and use your knowledge that worrying just makes things worse to try and improve. It's worth a try.
