I was in a similar situation.
Eventually, I decided to take control.
With Pay Day Loans I sent them a letter saying I could no longer pay,
I have stopped the payments (in reality I had to open a new bank account, which was a basic one with the co-op) and they were only to contact me by post, and if they did contact me by any other means I would report them to the ICO. This worked.
Eventually I took each one of them to the Ombudsman for unfair lending and one every case, getting the loans written off and recieiving refunds of about £6K.
This did take about a year in total.
I would write to the PDLs today and inform them you are planning to take the case to the Ombudsman and do so straight away.
While the case is with the Ombudsman pending an outcome, they can collect till the Ombudsman has ruled - this will take at least 4 - 6 months and at least will by you breathing space.
With the other loans, get in touch with National Debtline straight away.
I was with PayPlan for a few years and this held off the wolves while I was able to get myself straight again.
Also check that any lenders are actually able to claim the debts through a CCA or an SAR.
