Hi Nancy,
I dont see it as so much sin but more so that you have just been caught up in life and forgotten to show praises and faith in God. Its best to separate yourself from those who gossip and judge others as thats not going to serve you any good in this lifetime and for you to help others by doing social work and support based work, as you are naturally very knowledgable and also helpful, so naturally helpful to those you dont even know. You will start embracing more purpose in 2020 dont be hard on yourself and just let it flow to you naturally and it will late February of 2020, have a great new year to come
