Hi Vineeta,
Everyone takes breaks, specially women. Nothing to feel ashamed or depressed about. U may feel that others are doing better in the rat race but u know your priorities and at this point what u can can give to your family, no one else can. Your partner may not understand this, but have faith in your self. Everyone has rightly suggested that u keep yourself updated, at the same time this is the perfect opportunity to persue any hobby that u may have sidelined due to the work pressures. It could be painting, gardening, dance, reading, cooking ....anything. If u loose faith in your abilities then the whole world will do so, if u enjoy what u have, u will appreciate your worth.
Enjoy
