Probably first you should get a rough idea what you want to learn. When I studied Physics the standard track was Mathematics, Experimental Physics (Mechanics, Electrodynamics), Theoretical Physics (Mechanics), and then other topics, Wave Physics, Thermodynamics, Solid state Physics and Particle Physics. Normally first the experimental course comes and then usually with some delay the theoretical.
Still, you can decide if you want more Mathematics, more Theory or less. (Probably the CS Maths should get you covered pretty well for the start) I'd do a research on popular recommendations of books and then see which ones you like and interest - the styles and contents are often so different. While going through the books you can try to find nice YouTube videos and other stuff.
Of course you get a deeper understanding when doing some exercises, although this can be tough. I'd highly recommend finding a book that has a solution section/solution book or maybe some online course that offers that. The exercises for Experimental Physics are usually not long but can be surprising. ;) Also it might be surprising that depending on your interest a strong foundation in Mathematics is not critical, although you'll still need to wrap your head around the common math problems.
One motivating thing is that while you go through the topics (Mechanics, Electrodynamics, Wave theory, QM, ...) the frameworks and approaches are somewhat repetitive and just get more sophisticated over time.
TL;DR: pick a curriculum and combine it with your favorite material
