How to deal with the anxiety of moving in with a partner?

I decided that by the end of the year I want to move in with my long distance bf in NE. California cost of living is growing awful, i dont have any living family to rely on if things go badly here and life hasn't been particularly kind to me so I ended up with a huge late start on a lot of things. Things like job experience and driving, I currently have my permit and ive been slowly practicing with a coworker. My bf has genuinely given me the hope for a better tomorrow. We've been together quite a while. He says he can't wait for me to move in with him but i genuinely cannot help but feel anxiety about the whole move. NE pretty much requires you to have a car and even though he said we could share his, i don't wanna feel like im taking advantage of his kindness. I keep mulling over all the things that could go wrong, finding a new job not going well and other such things. I plan on having a year's worth of savings and a small emergency fund so im not dragging him down, but i cannot shake the anxiety of somehow feeling like a burden despite all these things. How can i feel more confident about following through with moving?
