hey hun! If you not sure i would say no dont go back friday as only you yourself will know when your body is ready and healed and if you are doubting it your probably not quite there! It will take people different times to heal so you may not feel as if you can do it at two and a half weeks where as someone else maybe able too. All I will say is don’t push your self! what i would do is get a plate at home or a couple stacked to the same weight as the ones in the restaurant and try walking with them and see how you feel
