I think there's some truth to being afraid to give up. But I can't see myself in any other industry, and I am proud of my work whenever I see it in production/being used irl. So that makes me think I'd always enjoy being involved with building stuff in some way.

In response to your last question, it might be both. I think my current job is a push factor, and the new field is a pull factor. As other commenters have rightly pointed out, I'm not enjoying my job. I don't know if that means it's wrong to recognise the signs that I might not be as motivated as I should be, though.
