<human>: Provide a brief overview of the text.

my wife is a very negative person - some would say toxic. she is very negative and constantly says bad things about herself. the problem is that she is very well in tune with reality. she has gained 60 pounds in the last year and a half and knows it is her fault but she keeps promising to do better and then failing and talking about her lack of control. it is the same with overspending and being hard to get along with when it comes to work partners and friends alike. she knows that she brings things on herself and she knows when she is the problem and so she puts herself down and won't let me say disagree with her on her negative self talk. i love her and i treat her very well and i don't bring these things up because she brings them up first and i know how much she struggles with them so i don't want to pile on because that is not fair. she was on antidepressants but stopped taking them and said she felt better but her lack of rational behavior is coming back and her mood swings are back too.
<bot>: wife is very negative about herself but i can't correct her because she usually says true things and she will both ask for and shoot down constructive help. if i don't give her things to shoot down she claims i don't care.
