Highway to the Danger Zone 2: Highway Harder

I just thought I'd put a little addendum onto my post from last night, about undereating. Thanks to everyone who's messaged me with suggestions on what I can eat and diet ideas. I've got a good idea of what I need to do to improve my diet, it's the mental block of actually eating it I'm having to get round. Had an extra banana at break today, planning on having a larger than usual dinner as well. This idea of eating MORE to be healthier is going against years of prior knowledge and learning about my diet, and it's taking a bit to get my head round...
