hitting the wall

y'day i hit the wall. woke up so tired and went to the gym. slogged through the recumbent bike and did all my arm / stomach exercises and started to do errands but rethought it. i was so tired i came home and just slept in my gym clothes. i hate doing that. i like to go to bed clean but i couldn't move. my bones were achy..they had told me that the neulasta can give you bone aches...it was really painful. makes the back, knees, hips all hurt. hard to walk normally. today i don't feel as tired but i just got hit with a wave of nausea. am heading to gym to try and work out the demons. this sucks....
