My SO def has anxiety and depression issues, but his paranoia is on another level. He is a germaphobe, always thinks people are talking about him, handles stress very very poorly. One of our recent fights was due to him not wanting to give my kids house keys (They are with us part time, less in my oldest case because of college). He claimed that my youngest (15 almost 16) would immediately run to his dad and show him the key and then his dad would make a copy and come to our house and go through our stuff. My sons father is NOT like that, it’s an absolutely bonkers scenario, my son is almost 16 and has had keys for his dads and my parents house for years already... it’s nothing exciting for him. 

So is paranoia or whatever this is part of anxiety?
