Has your parent attended therapy and was it beneficial?

I'm thinking of talking with my mom about her going to therapy. She's not an alcoholic but she is an adult child herself and my dad is an alcoholic (she left him 30 years ago.)

I think she might be receptive to it and my hope would be that some of the burden she places on me would lesson and that they might be able to provide some guidance for her.

She has no friends and struggles with family - I'm typically her sounding board and to to person which is challenging for me.

I wouldn't have any expectations on the outcome just trying to expand her toolset that doesn't directly involve me.
