Okay I am verryyy stuck on Zelda:Twilight Princess collecting teardrops...?

I am in Zora's Domain. And I'm collection teardrops, and I have all but two, and their locations are not on my map, I have looked through every walkthrough I could find, and checked all the places they should be, but idk if thats the right place, because I haven't found any bugs. So I need step by step instructions. Someone please help. I'm not sure but is there a bug in the city? If there is, I have no idea how to get to the city, because I don't have a portal to get there, and if I get that one, I'll still be missing one. There are no locations on my map, and no way to get to Castle City, and one bug, that I have no idea where it is. Please, please, help me. And don't give me links to game sites, unless its specific and can help with what I'm having problems with.
