Anxiety Overload

Does anyone else feel like you are two different people? I always think my "normal" head and my "anxiety" head is two different things, like the good and bad version of myself almost. This week I've really been struggling with my anxiety and I have just been irritable for no reason. Like really irritable. I know im taking things out on my partner and that he must be kinda fed up of me by now. I'm constantly worrying about how my relationships going, if I'm missing anything, I'm worried so much about messing it up that I think that's what makes me mess it up. I just want a break from my brain at the minute.
