Hey Girl,
Welcome to MF!!! I am glad you are taking care of your health and loosing weight.
For me, the first three days were the toughest
I almost quit so many times!!! However, I vented my emotions on here and received some great advice. I am happy to say that I got through it!
One thing I had to do my first week was not be around food and other people eating food--it was a huge trigger. I even told my mom that I couldn't go out for dinner with her and the family for her birthday dinner. I explained to my mom that I was trying loose weight and that if I was out with everybody, chances were that i wouldn't be able to stay on mf. My mom understood and supported me.
I am not saying don't go with your family this weekend, I am just saying that for me it was so darn important to get through the first week that I had to put myself and my needs first.
If and when you go to your in-laws, what about calling them first and telling them that you will be just starting a diet and tell them that you might need their support. For example, you might stay back if everybody goes out to dinner, if they have candy and stuff sitting out, if they could please put it away just for the weekend. Hopefully they will want to support you. But even if they don't, you can still get through this weekend--one day at a time. Just tell yourself that you only have to get through mf today--and if it gets real rough, tell yourself that you only have to get through the next hours. Also, when having intesne cravings, it is good to do something with both your hands and mind for 20 minutes. For example, organize your closet. If you keep your mind busy, it will be distracted from your cravings, and if your hands are busy, your body will be distracted.
whatever you do, don't give up on yourself!!! You are worth it!
Welcome to a life of no longer obsessing about food.
