First congrats on the 1 week !!!! WTG
Yup, there's nothing you can do about a slip except to jump back on the band wagon and try again. Listen, we all learn from our mistakes so chalk this one up. You are human and its going to happen again so don't be so hard on yourself.
Brush your knees off and start again. Maybe next time you'll be able to stop before making a boo boo.
HUGS !!
