I am sorry your H has filed. Continue to stay strong and keep living life as you are. It is easy to say "it's just a piece of paper" and reality for most is the attachment of emotions around the meaning of that piece of paper.
From your time on here you have made great strides to learn about yourself and overcome a lot of things that may have been holding you back. You are a strong woman, very capable of this and anything else life puts in front of you.
Contact your L and know that this is only the beginning of THIS process. You are still in charge of your life, just remember that there continues to be no way of predicting the future and what it may bring.
