Hi Ithi! I'm sure you'll find the support you need here. ( Don't worry, your intro is not long at all. Have you seen any of my posts?! I am, apparently, quite talkative.
)
I'm fairly new here, but determined to make this work, and that includes building a solid support base here. I hope I can become a part of yours!
I definitely understand a few of your obstacles. When I was young (21) i also moved to another country to be with the one I loved. We were happy, and that made us both too sedentary and careless about our food intake. We also spent a bit of time living with his family, but even once we were living on our own we spent most nights eating dinner with them. It is tough when you don't have all the control over your own food, and how it is cooked!
Here are a few of the things I managed to do when I was in your situation:
-Walking. I found that extra walks, sometimes with family members, sometimes on my own, helped even when the food I ate wasn't exactly healthy.
- Chores and Yard Work. I found something extra to do. This helped me be more active, and made ALL of us who lived together much happier.
-Help with Cooking. Can you offer to cook some meals, once in a while? Suggest you have a new recipe you think everyone would love, or offer to cook the veggies for the meal. Sometimes I had to word my 'help' just right, but often it meant I was able to cook the meat without excess fat, or not fry the veggies in butter like they would.
i'm not sure if any of those would help you, but maybe i've given a few ideas you can work with. I hope you're able to implement something that helps you feel better about the process, and yourself! Good luck!
