need help saving blue color-infused orchid

[ComplexVixen]

all! My name is Holly =) I am new to the care of orchids in general! that being said, I have 2. one that had broken that I repaired w wax. I will attach photos to show u where the issues are. not sure if I should cut down to the spike where it has turned brown now?? or leave it be?? It only bloomed once since Ive had it....now I am assuming it is in its "resting stage"... Yikes! what do I do?!
