After I have received a notice of acceleration of mortgage - can anytjhing be done to stop foreclosu

Sure, you can stop the foreclosure by curing the default, which means bringing the loan current. This means paying all the overdue payments, late fees, legal fees and any other fees set forth in the notice of acceleration. If this is impossible, you might be able to negotiate a forbearance or loan modification but it sounds unlikely that the lender will consider these options if notice of acceleration has already been given.
