I can relate to the experience of finding everything is totally different now to how it was before you took a break. I was a self-taught developer who then took a lengthy gap to do a PhD and postdoc. That ran into a dead end, and after much reflection, I decided I wanted to get back into coding. My blog has several posts about this thought process which may or may not be helpful. To cut a long story short, I did two online boot camps (one on Ruby on Rails, one on Swift iOS). The experience of coding with an experienced mentor that I could bounce questions off was really helpful, and I soon got that buzz for coding back. I'm now into my second coding job (as an image data scientist for a London fashion tech startup) and I'm loving it.

Please feel free to reach out if you think any of my experience could be relevant and you'd like to chat further.
