need smoking support

I need you ladies! i used to smoke about 7-10 cigarettes a day but I quit smoking when I found out I was pregnant. I'm in my 3rd trimester right now and I'm so stressed that I started again...About 1-3 a day. I don't want to hurt the baby but I am having such a hard time coping. I'm coming here for support and stories...not haters. please don't say horrible things bc I'm very down in myself right now and feel like a failure. I just need some insight from you all. please some words of wisdom!
