a friend gave me a lovely orchid last year, it was lovely until flowers fell off and some people at work found a pleasure in removing the things that covers new buds/blossoms (i dont know the right term)

anyway, its been more than a year and no flowers till now, there are some rotten roots and new one, i have been reading alot online, and i got very confused so i decided to ask for help from experts, i have read in a previous post an advice to cut the orchid above the last nod and seriously im too scared to do that so i decided to show you my orchid, please help me ...
