My pvp equipment manager items are missing!!!!!!! *item missing* t.t

Today when i log in my paladin account, i notice that my tank spec and PVE gear is not right. I saw my HP was lower and some keys and macros are gone and broken. So I use my ITEM MANAGER and use TANK, but the HP is not right. So i use my healing spec and back to TANK spec, and it fix it. But the icons are still missing and macros. To make it short i fix all my tanking spec, talent, keys and macros. So i go to DS and tanked morchok, After that the leader told me go heal, so i use my heal spec... then I realize my PVP gear is not on my bag. MY pvp Healing gear was gone missing.... The ony thing left was my Cata Trinket ,and CATA relic (pvp) the rest was gone. Please someone comfort me T.T or help me fix the ****in problem.. It broke my heart .........
