Hey @infidel1258, you have two options here. Both easy in their own way:

First up - use steemworld.org/@infidel1258, find the delegation section on the left hand side, look for outgoing(I'm sure it's called that), find the account you no longer want to delegate to and press the ❌. Hey presto, delegation returned in (I think) 3 or 5 days.

Option 2: simply delegate 0 (zero) to where ever you are delegating at the moment and that will return all your delegation. If you only want to take back a certain amount then just delegate the amount you wish to remain, and the rest will be returned (again 3 or 5 days...)
