No, don't give up girl....just try to find a way to use the time you have for your benefit. Don't let not being able to get to the gym keep you from exercising. If you can squeeze in 15 or 20 minutes in the a.m. when you first get up, or any time during the day, maybe you could do some floor exercises (ab crunches, push ups, situps, leg lifts, etc.) or on any of those days you could find a spot where you can go for a power walk. I know that changes in schedule can really throw a person off and it is hard to find a balance again, it may be a bit challenging, but the rewards are SO beneficial. Not only physically but mentally too.
And remember even if you cannot control the circumstances of getting to workout, remember that you CAN control your food options. So if you miss a few days of working out, just try to counter it with continuing to make as healthy of a food choice as you can. I know that is especially difficult when you go on vacation, but it can be done (speaking from personal experience with all of this).
Good luck, I hope your Grandma gets better soon! You are very sweet for taking care of her
