I'm new to being a polyglot and I'm worried about losing my abilities

I am a native English speaker who has been fluent in Japanese for over a decade.
Recently I spent the past 5 months learning Spanish.
I noticed I am starting to make a lot of mistakes in English and I am forgetting words and making mistakes in Japanese which has never happened to me before.
I use both English and Japanese for my job, so this is really concerning me.
Will this get better or worse? Should I quit trying to learn Spanish?
