Perhaps you've taken a day off from your meditation practice. Perhaps it became a week and stretched over months. Perhaps you've fallen off the cushion.
You're allowed to forgive yourself. There is a lot to be distracted by, more all the time. You're allowed to forgive yourself for not being able to forgive yourself. It is easy to quanitfy and grade yourself and to feel badly when you don't believe you're the best. It is quite hard to think otherwise.
