PLEASE HELP

So I had a little over 1,000 photos on my iPhone. I let my little sister play with it and somehow she ended up in the settings and she turned of the ICloud. This made me lose over 800 of my photos. I turned it back on and everywhere I look it says I've used up all my storage saving 1,057 photos. That's about the number I had. Now it's not downloading any of them! I've done every online thing I can find yet theyre not downloading. When my sister turned it off I had 227 photos in my album and now it says I have 327 but I don't know if it's downloading them slowly or if I can even retrieve them. Please help me! Those photos are my memories. If there is anyway I can get them back please let me know.
