Games : Can I get a save game in skyrim on 360?

So I was playing skyrim and I wanted to marry mjoll but didn't know how to I looked it up and found out you had to be kinda high lvl, so I go to my pause menu save my game on my current character delete the auto saves, and I THOUGHT I went to the load section on the pause menu so I go to the save where I beat the dragonborrn main quests and almost finish main quests so I press the button to load and I see it says saving... So I flip out because it took so long to beat miraak in the dragonborrn quests anyone know how to get that save back? 😶😐😢😭
