You will need to take advice before you declare bankruptcy, to make sure this is the best option for you and you don't qualify for a debt relief order. There are other issues too so I suggest you contact one of the experts on here or visit the CAB for advice.
I feel that if you are unsure then you should pause and seek advice - CAB is free and often useful. The experts here are excellent and will advise you.
In any event, you will need to seek advice and the DJ would ask you that in court
