It's hard to explain how this has developed exactly, but basically when I was a bit younger a couple things happened that made me feel very paranoid and anxious around other using tech. I was accidently outed because one of my texts showed up on my mother's phone (we had some sort of linked account), and several times out of the blue they said that they had been watching what I was doing online (I'm certain they didn't, as most of what I was doing online at that time was spewing heavy depression stuff). Anyway, all of this has over time made me feel very uneasy when other people are using their phones or computers around me - I'm scared that things I'm doing will show up for them, that they are spying on me, even if all they are doing is logging onto our Internet. I know that rationally that's not the case at all and that even if it did I have nothing to hide, but it still makes me feel very anxious all the time. It also makes me easily irritated when anyone talks about getting a new device or using an older one, as the whole set up process sets off alarm bells in my head. It doesn't really make any sense why I feel this way, I know. 

But I don't want to keep feeling like this and having anxiety attacks just because someone buys a new phone, over tiny incidents that happened years ago. Has anyone experienced similar things, or have any clue how I can get rid of this anxiety?
