There are a million reasons to fail, and only one reason to succeed (because you are worth it)... luckily the million reason reasons to fail don't matter, but you do.

OK I am going to just say what I am thinking... stop looking to these people for approval and look within yourself and what you want and what makes you really happy. Stop defending yourself and your decisions. Your success will speak volumes to these naysayers. I would also make it a point not to share a meal with these ladies until you are at least in P3, when your diet is less restricted and you no longer feel the need to seek their approval or support for what you have decided to do... plus by the time you reach P3, there will be plentiful evidence of your success and your confidence will have grown. If anyone in this group comments positively about your weight loss, simply say thanks and move on to another subject, if they are negative or ridiculing, then excuse yourself from their company. I would make it clear should this subject ever come up again, that no matter what decisions these ladies have made regarding their own health and weight loss you may not have agreed with them. However you respected those choices and tried to support them, and you expect at least that much in return from them. They don't have to like your weight loss plan, but they should at least try to support you as you work through this process.
Living well and looking well is truly the best revenge. You also need to realize the moment you lose weight and become "an equal" to them, the playing field is level and they can no longer make themselves feel superior at your expense... plus all eyes will be on you and you will get the attention... ahhh insecure people can be so pathetic.
