oh loza, its not a good time for many at the moment, but yu do have a chance of being emplyed again, though you wont get maternity pay from your new employer.
is the mortgage in your name? i presme that the bills arent just yours and that your partner does pay towards them. our joint earnings will obviosuly be taken into account when applying for any benefits.
you may also get a maternity grant from the government if youre on certain benefts, which is �300 i think.
