Parse error – CANT LOAD DASHBOARD

I made a change to my themes Editor and before I was finished, I accidentally clicked to Save. Now I cannot even get to my dashboard to correct it! The error I get is below:

Parse error: syntax error, unexpected ‘function’ (T_FUNCTION) in /home/content/p3nexnas05_data01/28/2105028/html/wp-content/themes/pinboard/functions.php on line 26

PLEASE HELP! I just want to reset to the default and I realized I was in editor and not Custom CSS! I am so afraid I just lost everything!
