Help me please!

I know

If your caning loads of drugs at the weekend (ket, pills, booze) you won't feel like eating much.

That's why photo forum looks like an advert for the malnourished.

TBH I dont do stuff very often, once a month isnt enough to cause me to loose this much weight. Ive drank loads in the past week, but I was teeny tiny prior to that. Ive got into a habit of skipping meals and generally not eating, but Ive only just realised it and its obviously been going on for ages now!
