I was scared of reflog too. Had to use it for the first time recently after I accidentally'd a branch that I hadn't pushed to remote yet. I was so glad that I could recover it all in <5 commands.
Title text: If that doesn't fix it, git.txt contains the phone number of a friend of mine who understands git. Just wait through a few minutes of 'It's really pretty simple, just think of branches as...' and eventually you'll learn the commands that will fix everything.
