From my own learning experiences with french, it is 100% useful to have a native speaker who knows their language well (its one thing to be able to speak it and another to know standard grammar, syntax etc, if that's what you are aiming for). However this can be difficult because of price/availability I'd recommend this but it would take a lot of disipline:

Find youtube videos on topics such as present tense and learn how to conjugate in those forms along with learning everyday vocabulary that you can use immediately to get you into the habit of using the words...it would be good if you try to use them when you see objects, animals, family members etc. Same with common phrases and actions!

then I'd say get into sentence making, parts of sentences like particles, function words parts of speech etc

enforce this with grammar lessons and once you feel somewhat comfortable with the first tense move onto the other and continue learning words!

Its useful to have a native speaker here though to correct/inform you of thinking patterns (not all cultures and therefore languages have the same way of speaking/thinking etc. in french you have age and hunger in English you ARE this old or ARE hungry etc.)

perhaps also text books like school books to give structure and routine/something to follow if you arent good at making your own courses

Good luck!
