Hi @woowoo and a warm welcome to the Community Forum 
Every time we are emotional when we have to say goodbye but yes it will get easier for you. I completely understand how hard it is after having built up an amazing bond with an animal and then having to say goodbye. Try to focus on the amazing times you had with them and then focus that emotion on to your next sit. Remember you are certainly not alone with these feelings.
