Welcome! You'll find this place to be the haven you were looking for. I've only been here a few days but I'm finding this place more and more helpful! Your trainer was definitely looking out for your best interests.. the ladies on this forum are incredibly helpful and supportive. Just reading posts from people doing so well has kept me pretty motivated.
I definitely agree with Zoseph! Keeping a positive attitude about the weight loss will definitely help a ton. It sounds so simple and like you actually arent getting advice something you already know.. but its very hard to get into that "YEAH! I can do this!" positive mood. Everyone here does a really good job at pushing you up and helping you along! Definitely keep in mind how amazing it will feel to post in the goal thread! Or finally fitting in those size (goal size) jeans that you've been dying to be able to!
Anyways, good luck and definitely come here when you are feeling down! There are so many different spots to enjoy, theres always something to do
