I hate that I can’t do anything to help my wife

My (36M) wife (37F) has PTSD, diagnosed with borderline personality disorder, and fibromyalgia. We got together four years ago and have had our ups and downs. She is the kindest and most giving person I know and I love her so much. But I feel like I can’t do a single thing to help her. <br><br>Everything I do is so minor. I take care of the pets, pay all of the bills, cook the majority of the meals, do the majority of grocery shopping, buy her gifts, tell her she is beautiful, hug her a lot, give her massages, send her texts telling her I love her and that she is amazing, spend hours answering questions that she has, etc. But she always worries about me being unhappy with her. <br><br>I know that her problems are mostly caused by her borderline. But it feels like it is never enough. Like I can’t do enough, give enough, to help her. I don’t know what to do to help her feel loved. I love her more than anything. But it feels futile. <br><br>I love her and I don’t know what to do.
