Sorry to hear that things are a bit rough lately, I hope you're starting to feel better now. I understand what you mean about the birthday thing, some years I have great birthdays, and some years I just feel so 'blah' about the whole thing. I'm not too sure why exactly, sometimes I think they can be a bit overhyped and they never really live up to the expectations. So don't feel too bad, I'm sure a lot of other people feel that way sometimes too
Re: your diet - the best advice I have for you is just to focus on making each meal as healthy as you can. I never really used calorie king to begin with, I just focused on using common sense, and trying to eat meals that I thought were good for me. So for example, I cut right down on the junk food, and tried to focus on the basics: like eating 5 serves of vegetables a day and 2 pieces of fruit, some lean protein and no more than 2 slices of bread a day. The weight started coming off for me, just by following simple steps like that. Further on into my weight loss, I started getting a bit more specific and looking things up on calorie king to see exactly what i was eating. This was particularly useful if I was eating out somewhere and wanted to know how many calories were in specific types of foods. To this day though, I don't actively enter everything that I'm eating into calorie king, I just use it as a general guide. Some people like to enter everything though, and it has really worked for them. I'm not knocking calorie king in anyway, it's all about finding a balance and something that works for you
re: your ex - Try not to let it get you down, I'm sure there is a reason that you guys broke up, and that underlying issue is probably still there after all this time. It may sound harsh, but if he broke your heart, you're probably better off without him anyway. You'll find someone that treats you well, and that won't break your heart
Wait until he hears about how fabulous you are looking this time next year!
