£1000 in debt

What can I do? I'm £970 into my overdraft because I had to resign from my job last month due to not being offered work accomodation anymore.

I am looking for a job currently but being 29 weeks pregnant and at a high premature birth risk it's becoming difficult because my midwife says I'm only allowed to do limited things and doesn't want me working past 34 weeks

Ive moved back in with my mum for the time being and she's not making me pay rent ect which is really nice of her.

I have capped my overdraft so it can't go over £1000 but now I'm not getting paid what can I do to get out of it??

I should be getting £250 a month from universal credit from September 8th but obviously that's barely going to touch it! If I get my £500 maternity grant around the same time that will help a bit I suppose but not much (ps I bought baby everything he needed before I stopped working so I don't need to spend that on cots ext because he has it all)
