Everything except characters was deleted

I logged onto borderlands 2 today and the only thing there was my characters. My B.A.R. was gone, heads/skins, all my settings were reverted. Is there anything I can do to fix this or am i just stuck with this.

This means that the profile save (which is independent of each character save) some how got corrupted - maybe during your last session if you had any kind of power or internet disruption while the file was being updated.

At this point, there’s probably not much you can do other than file a support ticket - the folks at support may have some things you can try, and can also help out with BAR and keys.

The unlocked heads and skins are a different matter, unfortunately, unless you happen to still have access to some original BL2 360 saves and can re-upload them to the Handsome Collection version.
