if there's any way you can have practice talking/writing in french, like Duolingo or a pen pal, definitely try that!
to get used to sentence structures and tenses i recommend watching a tv show you like in french with english subtitles--it highlights the difference between English and french sentence structures, similar with music. The inverse doesn't work too well unless you're decently fluent but it's always worth a try.
i'm not fluent yet but i'd be more than happy to help you out with practice if you want.
