Hey Calamity
I think you've answered your own dilemma in your post :
"I honestly don't think I can do this anymore. im scared to death of losing my house but I don't think my health can take much more."
If your health won't take it, you won't be able to work.
You're very stressed, and overworked, and that's not helping your health.
If you stop doing this due to health, there are options to take that won't necessarily mean you lose your house, the trick is to know when to call it a day before thongs get so bad that you have no choice but to stop, and are in no condition to explore the options.
I would suggest you seek advice on where you stand financially from the Citizens Advice Beur... wossname, (Can't ever spell that word!) for example, can you claim carers allowance for looking after your mum?
When you're ground down, things look far more grim than they actually are,and you feel like a rabbit in the headlights
. Small steps towards making a decision that is right for you is often the best way forward. I think you know what you need to do - it's exploring the options that can give you hope for the future.
All goods thoughts sent your way...
