Before I start, I feel horrendously guilty for posting but I've spent most of the night awake stressing and it can't continue. 
My wonderful DM is having some serious financial shit ATM. She has a works pension, a pt job and low rate DLA. Due to starting a job in Oct, her money is completely messed up. She gets barely any pay from her job, they stopped her HB until they saw how much she'd earn and although she handed in her payslip just before Christmas, we are still being fobbed off about the delay as they have a backlog because of Christmas and NY. I have informed them that it's ridiculous to use 4 days of closure as an excuse for 3 week's delay and I'm
.we have applied for WTC because she works 16 hrs and is disabled and we have now exhausted any other monies she may be able to receive. She lives on her own in a large private rental and would be devastated to downsize.
Now DM is the most generous person going (too much so and in the past Dsis has used this to her advantage, unfortunately.) DM has helped me out of hole on several occasions and I don't grudge her a penny. I've covered 2 and 1/2 months rent for her but I'm now seriously struggling myself. I put a fair bit of shopping on my DP and my CC for her but this is racking up now and is fast hurtling towards 1k! He is completely understanding about the situation but we are all panicking about how DM is going to pay it back. She's 100% good for it and has asked us to calculate the interest accrued too, but I know it's going to take months to pay it off. She asked again yesterday for me to pay a bill on my CC and I can't say no. DP went pale when he heard how much she is due.
To make things worse, her mental state is rather fragile, she is talking about not wanting to 'be here' any more. she says this occasionally but thank God had never done anything. I can't say no to any more help. I'm very early stage PG after 2 MC and the stress is really getting to me. She won't downsize as she often has my DSis's kids and loves her home so much. I've thought about asking my aunt if she can offer her a loan to tide her over but it's only making her debt worse. I thought about trying to get her a crisis loan but again, it's only dragging the problem on. She is completely under qualified for the job she does and I'm working on persuading her to get another in her field. Due to workplace bullying, which has contributed towards her mental state (with physical manifestations) she lacks confidence in a lifelong career.
WWYD in this situation?
