Can you max out on the benefits of therapy?

I’ve been in therapy since 2012. Do you think it’s possible to max out on the benefits?

I am pretty stable emotionally and manage myself well, but still really struggle in relationships, boundaries and asserting myself — but I honestly wonder if it’s just a matter or me being uncomfortable and messy and trying to do these things, vs processing and learning at this point.

I’ve been in therapy since I was 18 and have spent over 60k on mental health over the course of my lifetime. I can say I’ve greatly improved from 2012 to now, it’s like I’m a whole different person, but has the benefit of therapy maxed out? I can’t help but wonder what a life without therapy would look like.
