Is it just me?
If I'm in a bad mood, eg due to tiredness, hunger or hormones, or I get v annoyed, most of the time I can't hide it! I have a face like thunder. It does tend to be more if I'm hangry or hormonal and I think I do have PMDD so my moods are affected by that but it doesn't seem like everyone is so moody or they can hide it better and put on a smile!
Anyone else?
