How to quit vaping?

I am quitting vaping: I have been vaping for 3 years. I am having the HARDEST time quitting. I get on the verge on passing out, I feel dizzy, I get tunnel vision. I do not feel normal at all. Like I feel as if I’ve taken drugs lol!! If I didn’t suffer such physical affects it would be so much easier, I can handle the mental toughness of needing to quit but I never expected vaping to affect me so much physically. I really need tips on how to do this, I’m struggling. What can I do to feel better? What could help with the passing out / dizziness? Has anyone experienced this while quitting?
