Hi, @Marie71. So glad you have joined this forum and are putting a plan in place to quit! There is information, community wisdom and moral support here that have helped a lot of people stop smoking, including me. I'm only at the two-month mark, so I can relate to the feelings of worry and dread you describe. But the fact that you have 46 years of NON-smoking life experience to draw on will strengthen your quit. You have already coped with difficult events and emotions without nicotine. You can do it again.
IMHO, any quit that actually happens is a good quit. I don't believe one method vs. another is superior. They all have pros and cons. I was a very heavy smoker, and for a variety of reasons the patch was my method of choice. It worked for me. If you ever want to talk about what that was like, I'd be happy to personal message with you or start a separate post/thread about it.
Quits that stick require us to wrestle with the fact that smoking is an addiction. There are emotional and social dimensions of quitting on top of the chemical withdrawal to manage. That is why it's useful to line up a support system (friends, family, support groups, therapists, whoever you can trust to be kind and patient) as part of a quit plan. For me, this QuitTrain forum has been especially helpful. People here "get it."
The emotional, physical and mental pain of quitting is real - I won't minimize it. But it does not last forever and it CAN be overcome! I delayed quitting for many reasons, but among them was fear of failure - fear that I would be overwhelmed and unable to handle the withdrawal distress. In retrospect, I think my nicotine addiction distorted that thinking and fed me fear to keep itself in control. It was not an accurate self-assessment of my ability. We are all - every one of us - capable of so much more in life than nicotine wants us to believe.
