Hello! To provide some info, I have anxiety, specifically social anxiety. But, one thing that's been happening lately is that I have the feeling to check things over and over until I know that it's in my mind and that I know that thing. I can't really explain it.
For example, this sounds silly, but when I have to change to my gym clothes in gym class, I have these thoughts running through my head, such as "are these clothes actually on me? am I just imagining that I'm wearing clothes?". I have to check over and over that I actually have clothes on. I would grip my sweatpants and force myself to feel the fabric, look at myself in the mirror, anything that would make me realize that I'm not imagining the clothes, they're a reality, they're on my body. But I still would have this fear/these thoughts that I'm walking around without clothes on.
Another smaller example is that I feel like I'm forgetting something. When I go to school in the morning, I feel like I'm forgetting something at home, although I know for a fact that I have everything I need, I did everything I had to. So I check to make sure I did all the homework I had to, or if I brought my supplies with me, although I know that I already have them.
I mean, just last night I was worried about this field trip tomorrow. I'm not going to school for it, it's a science workshop/conference thing with my teacher. I was thinking about if I had the papers me and my mom had to sign, if I knew where we had to meet up, what time we were leaving, all that. I knew all of the information already but I was worried that I actually didn't. So, me being me, at 3 AM I had to check the paper. As you can probably already guess, I already knew the information.
I wasn't always like this. It started happening recently, about a couple months ago, near the end of 2017. I'm not sure if this is just my anxiety acting up, scaring me into thinking that I don't actually know anything. I would appreciate it if someone could tell me if this is just my anxiety or something else.
