Ah but thats the whole problem with mental illness, its not like a broken arm or leg, its hidden and even when its diagnosed some coves pops along and says "oh pull yourself together", blah blah blah. Mood swings in sufferers can really con on lookers, one moment they can be laughing along with the fun but then in the loo crying their heart out unseen.
Lee is backing himself deeper into a hole, he cant see himself getting out of it, the only person who has an inkling how to save him is Johnny, but all he has done so far is drive Lee deeper into the pit of despair.
Its a good story line and depressing as it may be its on the money so far.
