First of all, welcome to 3FC!
We're glad to have you!
Do you have a plan you're following or would like to follow?
Second of all, you've had a lot of major life changes, which is stressful by itself! And I think a lot of us understand that not feeling comfortable in your body can magnify all of that stress so much more. But I encourage you to think of it this way: you are working at this very moment on changing your weight and getting down to a healthier, more comfortable weight for you. That's something pretty awesome if I do say so.
To answer your question: start doing something RIGHT NOW. This very moment. It won't be easy to start (it never is), but it gets easier the longer you go. It will never get better by doing nothing, and the unhappy mindset itself can be improved by taking action (even if you really don't feel like it). Do you have a plan? Make one. Stick to it all the time. Every single day. Stick with it when you're happy, sad, sleepy, excited, getting groceries, vacationing, working, relaxing, when it's hot or cold, when it's Tuesday or Sunday. Stick to it no matter your mindset - make it habit. That is the way to do this. When we give ourselves permission to veer off plan, the plan stops working (seems obvious, but I need to remind myself of this often). It is completely possible.
I eat in response to emotions, too, and it's not great. I'm looking at a year to get to where I want to be, too. If I had just stuck with it when I started last year, I would be a few months away from being done now. I didn't. So I still have a year to go. That year is going to pass no matter what I do, so I would do way better to spend those 365 days losing weight gradually rather than gaining it. By this time next year, I'll be so, so glad I did.
