I know how you feel. I tried to quit smoking exactly 19 times, very serious each time. I remember I was using the gum once, and a dear relative in health care said, "Our doctors all laugh, and say you're just mainlining now!" I didn't know anything back then, felt bad, you know I don't mainline anything, so went back to smoking. As it turns out, I do care what people who are close to me think and feel. The others, meh, not so much.
I have since quit smoking and vape. I didn't know a lot just a short while ago, but I think I have a good understanding now. Between this forum, the wife who quit with me by vaping, and at least 100 videos, I know a lot more. I didn't know that I would learn about the scientific studies, the composition of vapor, the good medical effects of nicotine on the body, the immediate health benefits of quitting smoking, and the science and chemistry behind vaping. I know that stuff now, and the others don't. They are ignorant, entitled to their opinions, and I have many friends here, and at home, who do support me. I have gotten a dozen folks into vaping, six of whom have quit smoking completely. I try to help the noob's with their questions, and myself with my own. I feel pretty good about it now, and I don't think those closest to me, who's opinions I do value, have learned a thing. But I know the truth, and that gives me comfort and strength.
You'll find that here Penny, and you can feel good about yourself, and about quitting all you want, and we surely appreciate what you've accomplished. Welcome to ECF, congrats on quitting, good luck, great post, vape on!
