Need to Borrow a Car Temporarily - TX

I wrecked my this week (NOT MY FAULT) and can't afford to get it fixed. I have a loaner but don't know when I will have to return it. The other woman's ins. co. has refused to pay for the damages and I cannot afford to pay through my ins. co. because of the deductible and increase in my monthly rates that that will cause which I cannot afford.

I have a three-day pet-sitting July 31-Aug. 3 and a two-week pet-sitting Aug. 19-Sept. 3. It is not feasible to take the bus due to having to be at the second pet-sitting three times a day at certain times and the bus on a schedule different than those times. Plus I have a and to take of of my own so it is not going to for me to stay at their house, not that that is an option anyway. Plus I could not afford to pay a sitter to take of my while I do that.

If anyone knows anyone who might let me borrow their JUST FOR THOSE DATES LISTED ABOVE, please let me know ASAP. Obviously I will keep in it and keep it maintained while I borrow it. I have insurance obviously and I can provide references if need be.

I know this is asking a lot but I am desperate. I cannot afford to another or get mine fixed.
