Dear Abby: 37-year-old woman is her stepmom’s ‘go to’ person and she says it’s getting old

DEAR ABBY: I am a 37-year-old woman who seems to be the go-to person in my family to figure things out. Due to my stepmom not feeling comfortable enough with her English and my striving to win her approval, I made sure to take care of the things she couldn’t from an early age. The problem is, while I used to be proud of myself for always being able to figure things out, I no longer feel that way.
There are five siblings in total. We are all adults now, but my stepmom seems to come only to me to solve any issues she has. If anyone does offer her assistance, she’ll say something like, “That’s fine, but I’ll just ask your sister instead.” I understand this may be my fault because of my incessant need to please her.
Lately, however, I’ve been struggling more and more with feeling used, as if my worth is dependent only on what I can do for her. Is there a way to change her expectations without having to tell her outright how I feel? — TOO HELPFUL IN CALIFORNIA
DEAR TOO HELPFUL: You might find it easier to start by being less available when your stepmother has a “honey-do.” She may be shocked and not like it, so be prepared when you tell her to ask one of your siblings. The alternative is to be completely upfront with her about your feelings, including the fact that you feel she values you only because of what she perceives you can do for her.
Being the only “adult” in the family is a terrible burden to be placed on a child, which appears to be what has happened to you. I knew someone like this. Like you, he was the designated problem-solver in the family. Sadly, no one was grateful for his efforts. Instead, they not only took advantage of him, but also resented him for it.
Call a halt to this scenario before you start to seriously dislike your “helpless” stepmom.
