Yeah warning them will just worry them and there is a chance (although small) that I wont get so bad next time round. Considering the last 3 ended me up in hospital I dont hold much hope for surviving the next one. Im so tired I can barely breathe, and every breath is painful. Maybe a nap and wake up feeling better? Doubtful, and more sleep = lower mood. Cant win. I keep reminding myself I can compel my limbs and muscles to do the good and right thing (going to the convention) despite my feelings but its not very effective yet.
