Without knowing the real circumstances, I would start from letting her know and showing her how loved she is and how much you appreciate the commitment she has made by leaving her home country...................Why does she have low self esteem???and feel useless??
As I say for me it would be to let her know the love and honour that you have for her, reasssure her, and go from there, to be honest if she's 26 she's still young and has made an enormous leap of faith by coming here...........without knowing the circumstances thats my opinion.....Take care
with the others' responses. It could well be she's suffering from some form of delayed reaction to a number of factors ... for instance, I've just been reading the *thread posted by your wife last autumn - at which time she'd been in the process of applying for her spousal visa. In *it she highlighted conflicting evidence with regard to the receipt of your divorce papers at the British Embassy in Manila. Clearly, the matter was quickly resolved - since she came to the UK on October 18.
consider this: As a young woman in her mid-20s living in the Philippines, it's doubtful she'd had much [if any] occasion to venture far from her familial surroundings - yet suddenly she finds herself uprooted to a "strange country", thousands of miles away from the only lifestyle she's ever known. Then, within a few short weeks, the UK was plunged into one of the most 
winters for more than a decade.
But I should imagine there are likely to be other Filipinas within reasonable travelling distance - especially if you are a town or city dweller. Encourage your wife to go out and make new friends ... (they needn't necessarily be of the same nationality!) 
... because (as you and I both know) Filipinos are very sociable people who have a natural ability to mix well with others and can integrate themselves with relative ease into whichever communities they choose to settle. Admittedly, MY wife is twice the age of yours - but you'd be amazed at the number of people who have befriended her since she arrived here in Perth just over a year ago! So talk to your Mahal ... about ... well, anything and everything ... in the way you probably did when you first met; perhaps suggest she might like to become involved in voluntary work, for example. And above all show how much you love 
and cherish her. 
you to our midst.
