Best advice I can give is come up with a schedule. Even for the small things. I had a schedule on my way through Wanikani, and I have a schedule now for grammar. Set aside time everyday and do something. Reading, grammar, listening… you have plenty of choices. Doing something is better than nothing.
Also, are you actively studying grammar? That will help. If you need a resource we have a thread here on Wanikani specifically to find learning resources.
The best thing to remember is to not give up. You can get it if you try. For instance, I started to learn Japanese back when I was a senior in high school. That was back in 2012. Seven years latter and I’m still struggling. It’s a matter of persevering. Tell yourself you can do it, and you will.
Good luck and don’t give up!
頑張って！
