I guess it depends what you want in life....
If you want you and your family out of the cult, staying in it wont help. It wont be easy, it may take time, so bear that in mind.
why not sit down with your kids and tell.them how you feel, dont commit to anything and test the waters. Do a slow fade if the kids are not likewise currently doubting. I get the sense, especially in the UK and USA that more than ever people are doubting and questioning. I have always seen the first member of the family that leaves of their own will as someone who the others can talk to, seek advice and follow out of the fog of misinformation.
If you decide to do that, it is very important to be very informed so you can show then where and when Watchtower lied and how consistantly they are wrong and misinforing their followers.
