Allow things to fall away if they aren’t right for you anymore. You can still love the person, experience, place, etc. and there doesn’t need to be resentment, but allow yourself the chance to continue growing when you know it’s time.
Not everyone needs to understand and not everyone needs to be supportive. And it’s very true that possibly not everyone will be. But when you know you are making the right decisions when choosing a new chance at growth, the right people, experiences, support, lessons, guidance, etc. will always come along.
Don’t be afraid to continue growing.
