get hold of yourself vs. pull yourself together

[Lilish]

Hi everyone
How close are these two expressions are can they be used instead of each other:
Pull yourself together and get hold of yourself
when we want to tell someone to control himself;not to get angry;to behave himself not to lose his head

'Pull yourself together/get hold of yourself/get a grip (on yourself)' are indeed interchangeable as they all mean 'control your emotions' or 'calm down'.
