Wow what a story, I am glad you are doing well.
Smoking is an evil habit and once that nicotine addiction hits its hard to get away, I smoked for about 11 years, which 9 was as a full time smoker ("needed" to smoke everyday), I quit about a year ago for the second time, after a medical scare. It was hard and I got a lot of cravings, but I got through it.
What was different about me, I started smoking after female journey began, quit for first time briefly (about two months) when I had SRS,but the cravings got to much and started again.
Anyways off topic
I am glad your mother accepted her new daughter with open arms.. I have a similar story when it comes to parent acceptance. My father did not accept the fact his son was a girl, my mother kinda backed her husband. He passed away without ever accepting his daughter. I was basically disowned. Some time after his death, my mother reached out to me (by now was about 2 years on hormones already), we started talking and after a while reconciled.
I learned, that she felt guilty over my issues with my gender, as when she was pregnant with me, she really wanted a girl. She was scared this affected me somehow.
Now we have a close mother daughter relationship, she tells me she loves having a daughter. When she married my step father, i was even a bridesmaid with my two step sisters. My step father and 3 step siblings (2 step sisters and a step brother) (I am my mothers only child), dont actually know I am trans or was born a boy.. By the time they came into our lives, I was already post op. I am not that open about my past. Only my female Bff, my husband and my mother know that I was born a boy.
I am was glad my mother was there on my wedding day (my something borrowed was her pearl necklace, she actually wore it on both her wedding days and my step father walked me down the isle. She actually told me, when she was helping me get ready, that when I was born she never in her wildest dreams did she think, that she would be helping me put on a wedding dress on my wedding day.. but she was proud of me and loved me. I told her to stop, as I did not want to cry and ruin my makeup.
