The song says, "Take your burdens to The Lord and leave them there." We can get the 'take' but get confused on the 'leave'. Don't pick them back up, drop them! If it causes you grief, stress, pain, leave it. Start right there. L E A V E I T ! Practice that today. It doesn't mean that you are shirking your duty, it means that you are learning to live the life God gave you.
So enjoy your life and learn to give whatever "it" is to Him. enough for now.
