I don't have any advice on self learning, but I have been getting a MS in CS for similar reasons. I also have a stats degree, work full time, and struggle with self learning. For me, being in a structured program makes it easier for me to manage. Certainly not a requirement, but it is the way I learn best. Maybe look for classes you can take at a local university or online and see if anything grabs your attention.
