FIRST off I would meet with your doctor about your anti depressant meds. I suffer from severe depression and anxiety and some of the meds that I have been on made me GAIN weight. Maybe there is another med that you could try that won't if that is part of it.
Also I am a HUGE (no pun intended

) emotional eater as well. And I have noticed recently that I have now become obsessed with calorie counting. I feel horribly guilty if I eat anything that has over 100 calories in it. (i can compine 2 or 3 things to make my 400 cals a meal)
Maybe meeting with your counselor more often will help as well.
There has been MANY times where I have opened the fridge and noone was looking and was tempted to eat something that would throw me way off my diet but who would I be lying to? MYSELF!! And I have come to realize that I am WAYYY more important than that. I write down everything that goes into my mouth. Including just nibbles or handfuls.
As for the energy to get up and walk when it's freezing outside...I know the feeling. I live in South Dakota and we have 2 seasons. Winter and construction. LOL! But I park farther from doors at stores, I walk Walmart, go to the mall, take stairs.
This is the longest I have ever eaten healthy. I don't like the word diet cuz this is a life long change and battle. And diet seems like such a naughty word.
WE ARE ALL IN THIS TOGETHER. This site is amazing. When I am having a rough day I can sit on here for hours just reading and it does help.
