Hi Amy!
You have taken the first step. You're here, so
and I'm glad you came!
You know, for me, the only thing that worked was making a conscious decision to CHANGE MY LIFE. Overwhelming? Of course. But ultimately, for the work I put in to change my habits and lifestyle, I got a whole TON of great returns...not just in my size and weight, but in my sleep habits, skin, muscles, mood, and blood tests/health. If you take it one step at a time, it is absolutely possible to change your entire way of relating to food and exercise, and the benefits you get in return will make you SO glad you did.
I've found that there is nothing like exercise for beating depression. Just getting out of the house and getting moving was key, for me, in managing my moods...and in time, the exercise helped my weight loss, which helped me feel better too.
What sort of plan are you following? Are you exercising?
Settle in and keep posting. This is a great place for ideas and motivation.
