There’s this famous bit in Grey’s Anatomy where Meredith and Christina always tell each other “You’re my person.” It’s very sweet and an ode to true friendship.
It’s OK to lean on someone, to fall in love, and to be happy in a relationship. If this is your choice, and you are content - there is no reason to celebrate yourself.
Just remember, however bleak this may sound, you are your person. You will always be your person. When the going gets tough, people are unreliable. They disappoint often. You are the person who will be there in the end to pick up the pieces and move on. You are your person.
