Paranoia (???)

Hello! I've never been diagnosed with anxiety, but I didn't know where to post this since I'm new here.

Since I was a child I've always been very paranoid. I remember that in primary school I tought that a colleague of mine was living in my attic. Also around this age I was diagnosed with ADHD, and I started talking to pedotherapists (i'm not sure if this is how you say it in english) because I had really bad separation anxiety and enuresis (till I has 14 because i couldn't go to the bedroom alone during the night). There was also this time where I tought that my death grandma was watching me in my house (i've never met her btw). My mom had this photo of her in her bedroom and whenever i would sleep there (separation anxiety remember?), i would look at the damn photo and i swear she was smiling at me.
This are some "funny" examples of what my "paranoia" is like, but recently its been getting worse. Every social interaction that I have i think about the worst most violent scenario possible. I dont trust no one besides my close friends, mom and dad. (I would like to point out that during the summer there was this night where i tought my mom was going to unalive me during the night with a kitchen knife, even tho she is really sweet and I don't have or had any sort of drama with her, the thought just popped into my head). I also create plans of survival in my head that are quite agressive, which is not very smart since i cant hurt a fly.

Anyways, my main fear is someone entering my house during the night while i'm sleeping. I think about it everyday before i go to bed. Today my mom was threatened at her work (money stuff) and I cant stop thinking about it. I cant stop thinking about the dude coming into my mom's work and like...stabbing her or something. Or coming into my house right now and killing us. Or setting my house on fire. I'm kinda freaking out ah ah. I freak out over the minor things, so this that happened today is actually putting me in a state of panic. Like I freak out when someone is walking behind me when I'm waiting for the train, so now that someone is actually threatning someone thats closed to me I am ACTUALLY freacking out.

I just wanted to know if someone has had the same thouhts as me. If not, writing this and expressing what im feeling right now has helped me a lot, i feel a bit calmer.
Thank you so much for your help and i wish you the best <3
