Gigit, hows the leg and have you had the situation resolved with immigration yet? (a doctor with half a brain is going to find the nodules on your thyroid anyway ...) you're creating a situation where your metabolism is in the dumper by not getting the right treatment for the goiter. We're talking a 10% to 15% reduction in your metabolic rate, easily.
The reason you were getting flabbier is that your muscles atrophy from lack of use. Do little things as you recover (and start working out after you're back on your feet), even raising your leg up and down from the knee while you're sitting, doing curls and presses with cans of soup, etc.
There's a great site for women starting to work out with weights, and she specifically addresses not having equipment:

Great site for the beginning, seriously, cruise around, check it out, she really goes into eating, form, training when you're time is limited, etc.
Hang in there, Gigit, you know the old saying, that which doesn't kill us only makes us stronger!
