Just wondered if anyone has any advice, as I mentioned in my original post my brother's girlfriend is staying with us 3 nights per week. I am starting to feel anxious, as when she comes I feel really uncomfortable, I can't concentrate on anything and can't relax when she's here. I'm trying to stick to my routine but I just feel so paranoid, like she's watching what I'm doing. It starting to affect me physically because I feel so tired, I've got butterflies in my stomach and feel sickly. Even when she's not here, I'm thinking about her staying, it's just circulating around my mind all day, I feel like I've got no control over my thoughts because I can't seem to stop. I've asked my brother if she can stay over less but he doesn't want to upset her, because he thinks she'll take it the wrong way, which annoys me even more because it feels like he doesn't mind upsetting me. Is this OCD or just anxiety? Any suggestions would be greatly appreciated.
