Mom has cancer

Sarah • Mother of a 6yr old boy and a 3yr old girl and a baby girl on the way

My mom was diagnosed with lung cancer over the summer. She went thru radiation and chemo and is hopefully cancer free now. She won't stop smoking and she means the world to my 2 and 6 year olds. I'm not sure how to feel about all of this. My anxiety has gotten horrible and my head's a mess! Idk what to do anymore please help...
