you've done well, but there's room for improvement in your diet - you've said you feel hungry, but on that day you had packets of crisps, which i find to be little more than flavoured air as far as feeling full is concerned. can you swap those for ricecakes, a low-cal yoghurt, crispbreads? you might feel fuller by opting for something like that over crisps.
i honestly don't know how you manage 1200cals a day, i find that totally daunting. bloody well done for sticking with it, i bet you're so proud of yourself!

and so you should be!
