<human>: Hello

As the title says, I'm 23, I have a BMI of 42.5. I am 126kg/278pounds and 170cm/5foot 6. And in need of tips on how to do this.

I've had a very bad relationship with food since I know myself, always being more chubby, but my weight went really up around the time I was diagnosed with depression. 

I recently finished a very stressful period of my life (graduated uni and got unemployed) and I'm at my highest ever weight.

I am addicted to food. Food is my solution to my depression, to my stress, to my anxiety. I desperately need to lose weight, I can not fit in any clothing item I have and the shops do not offer much in my size. 

I have one month of slack now, until I move to the other end of Europe (East to West so hopefully I will have a higher variety of healthy clean food) and I really want to start my lifestyle change before I move. 

So here I am, at another point in life where I am trying to lose weight. This time I decided it's not a diet, it's a change in lifestyle. And I desperately hope I can do it.

Some stats:
According to the BMR calc I have a BMR of 2062 and due to a sedentary lifestyle that means 2475 caloric needs a day. It would mean I could maintain a 1900 calorie/day meal plan and still lose. But here's the pickle. Due to months of unhealthy, high carb+high fat junk and carbonated drinks I am noticing an aversion to real food. I want to slowly ease myself into this (if at all possible) in order to avoid an early "burnout". I'd appreciate any suggestions. Healthy snacks, meals and any tips to not lose discipline are welcomed.

Also exercise is definitely the next step, but in the 40C/104F weather I find it hard to even breathe when outside, let alone walk.

Can you condense the text into a few key points?
<bot>: Want lifestyle change, need help to ease myself into it as going "cold turkey" so to speak doesn't work well with my depression.
