Is this normal?

So I interviewed for a new job yesterday. I think it would be a really great opportunity, and the interview went really well. I would be making more than twice what I make now. But every time I think about getting the job, my stomach is in knots. I could not go to sleep last night because I kept thinking about it. I feel so incredibly guilty about the possibility of leaving my current job. It’s not that I dislike my job, for the most part I love it, and I work with awesome people! But the pay sucks. Bad!

I’m not sure if I’m nervous because the new job would be something different and a lot of new stuff to learn or if it’s a sign that I shouldn’t take it if they do want to hire me. Has anyone else ever felt like this?

I have never felt like this leaving any other job. At those I always felt it was my time to move on, or I knew going in it was only a one-year position. Is this normal? Do people feel like this changing jobs?
