tl;dr - You should definitely do it! I am around the same age, and recently made a shift from a sales career to coding. I started teaching myself python using treehouse (no affiliation) and then moved on to using blogs and such. I was doing this for a few hours a week for about two years, and then got an opportunity only a few months ago to join a small team as a React Native/Typescript Dev. The learning curve was huge for the first 2 months, and every day I felt so stupid, but a few months in and I am so glad I made the switch. I think that if you are really willing to put in the time and don't mind not knowing what you're doing making the career switch is totally worth it.
