Is this a quantifiable personality disorder?

I have known 2 people, my mom and step-mom, virtually my entire life and both seem to have very similar personality disorders. One characteristic is suspicion of others/ hyper anxiety. For example, my step-mom will go through my dad's phone and accuse him of having affairs with any female who contacts him including co-workers. My mom on the other hand was/is always convinced that I am on drugs. She would look at my eyes and try to tell me that I was on something and my eyes looked weird, etc. Another characteristic is being the go to source on absolutely everything. I recently passed out and broke my jaw. After going to the hospital and having them say it was a fairly common fainting spell caused by working/ working out in the heat my mom still would not believe this and was convinced it was because I was on cocaine. Me and my dad went back to the hospital to get the records from my blood test and they didn't test for any drugs because there was no suspicion that I was on anything. This however was not enough for my mom, from 1000 miles away she can diagnose a cocaine addict better than a medical doctor. May I also include that I am in the ROTC, which I'm sure would have no problem finding a cocaine addict in their ranks. My step-mom is the same way and after bringing my xbox to my dad's and using xbox live she was convinced that their computer was going to get a virus from xbox live. After looking up online and showing her where someone who knew much more about computes than either of us had said that it was not possible to get a virus from xbox live she still wasn't hearing it and was convinced that the end of their computer was coming. I'm not sure that this has anything to do with it but oddly they are both teachers. Also they both alternate between babying and yelling at their kids. I've been dealing with this basically for 20 years and although I'm out of the house I don't want my siblings to have to go through all this as well. Any help that anyone could provide me would be great. Thank you.
