My only reservation is
I was a loving and devoted mother to her and hoped she would realize that, especially after she had a child of her own. But I don't see that happening and I'm thinking of simply fading out of my daughter's life. I don't think she would miss me and, at this point, vice versa. My second husband's daughter and grandchildren love me. Rather than beating my head against a brick wall, I think I'd rather devote my energy to having a relationship with people who appreciate me. My only reservation is that my natural granddaughter will miss out on having a relationship.
ここでのreservationはどう訳したら良いでしょうか?よろしくお願いします
