I really know how you feel Karina! (((HUGS)))eta-I'm sorry if I don't have your name right!
I'm not seeing results as fast as I'd like either. But try to remember, this weight didn't get put on in a month or two. For me it's taken years

And you may not see the results you'd like before your family get-together, and I know that would bum me out too-but do NOT let their (possible) reaction cause you to go off the deep end and start another diet you know you won't stick to(well, you might, but I know for a FACT that I wouldn't!)...because what good would it do if you lost some weight quickly only to put it back on right after? It's very hard on one's health to do that.
Try starting to include exercising, if you are not already. I know for me I feel so much better-more stable mentally- when I exercise. I have much more confidence when I can feel my blood pumping, and my body feels alive instead of like a slug. I am HAPPIER. And I know that for me I *will NOT* lose this weight without exercising. It can help the weight drop much more quickly, of that I am sure.
You know, even if you don't lose much before you see you family again, if they can see how much less your eating-nos style!- they are likely to be impressed and give you encouragement that they can see your habits changing for the better. At least I would hope so. And if they don't, please don't let it get you down! You are worth the time it takes to get healthy and (most importantly!!) to STAY that way.
I am finally at the point where I realize its going to take me a while to get this weight off. I know that. I don't like it one bit-but you know, if I hadn't given up so many times in the past few years, I would probably BE at (or a lot closer to!) my goal anyway. That's why I want to encourage you to look at the long haul. Not as fun, I know, but much better as it's something that will STICK once you reach your goal. And then you'll be in the tiny little group of people who lose weight and KEEP IT OFF. How great will that be?!
