Sounds like it simply wasn't humid enough tbh ..
I have a simple way of dealing with it ..... next time he goes into shed ( usually they hide away completely for days ) then I start increasing the humidity somewhat by spraying the viv well daily ..... then as soon as the eyes clear and the colour returns I start spraying well TWO or even THREE times daily . They then have a perfect shed a few days later ..
As regards feeding .. if it's finished shedding it will probably be ravenous .
How and when are you feeding incidentally?
