Graduation caps get thrown up to celebrate a finish and a start in one toss. Every big change works like that.

Every finish is also a beginning wearing a different outfit, and the reason big changes feel confusing is that both are happening in the same hour. You are losing a routine, a set of people and a version of yourself, while gaining something you cannot see yet. Grief and excitement at the same time is not a sign anything is wrong with you.

When the next big change comes, let both parts be true. Say a proper goodbye to what is ending, since skipping that tends to delay it rather than avoid it. Then look forward, knowing the wobbly stretch in between is normal and temporary.
