Letting Go

Today was pretty rough for me. I went to work and had to say goodbye to someone who had become far more than a coworker. I am realizing now more than ever that people have various functions in our lives. They come through and make their deposit whether it is good or bad and we have to receive it and grow from it. Life is all about growth and I am experiencing growing pains for sure. I understand that certain people have seasonal roles. I understand that what was good for you at one point can also at the next point be toxic for you. I just want to know what do you do to ease the pain when you want to hold on and keep the ones that are good, but have to be given back? Enough rambling for now...
