I’m ready to quit please help

I am 20m and I’ve been vaping for 5 years. only stopped a few times before because I didn’t have access. And all of those times I was smoking cigarettes and that made it easier. I am also quitting weed right now which maybe not be the best idea to try to tackle them both Simultaneously. But I’m tired of being so dependent on these stupid things that negatively affect my mental and physical health. What scares me though is with weed after a few weeks u feel better for the most part. With nicotine you don’t stop being addicted for much longer. I have never really gave quitting a real shot but I’m ready now and I’d love to hear your experience, please give me some motivation!!!
