I can relate to feeling so self conscious that you dont want to leave the house. Although I dont weigh heaps, I have struggled with major depression for years. It comes back now and then but I have to be aware of it so I can tackle it head on. I always think that hiding in my house will fix everything, and eating bad food will make me feel better, but actually its completely the opposite. I live alone so I do sometimes have to leave the house! And when I do I feel so much better, dragging myself out of my pj's and into some clothes helps heaps. I often find just putting on some makeup and doing my hair helps when I have to face the world.
Also, "feeding my emotions" doesnt work either, it just makes me feel guilty for turning to food. Your body will thank you for feeding it something healthy.
I can understand your scared about the new diet. I love food too! I think thats why alot of ppl here say they are eating healthy rather than that they are dieting.
There are heaps of healthy recipe sites on the net that have great recipes. Often you can continue eating the same sort of things but just make minor adjustments to it. I live alone so making a quick stir fry or curry is easy for me. Instead of using sauce in a jar or curry paste and coconut cream, I use curry paste and skim milk. Still tastes good. And I just have it with heaps of yummy veggies that I enjoy instead of with rice that I find makes me bloated.
I find the best way is to experiment until you find stuff you really enjoy eating. Having fruit and veg for snacks is a great way to cut down your cals, so just find stuff that you love eating. I love strawberries and even though they are expensive I like to treat myself to them because I would rather eat them than something bad. I also love sugar snap peas, great to munch on! So just try snacking on healthy stuff that you know you love.
Anyway! I think I have rambled on enough. There are plenty of great tips out there to help you on your way. I really hope you can stick to it. Even just losing a couple of kilos can really help boost your self confidence. I find the fact that I am eating better and exercising makes me feel better, even if I cant see any differences yet.
Good luck! You can do it!
