I just ruined my diet . ways to make me feel better? :(

Your calorie goal may be too low for you.
Reevaluate your goals and pick something less aggressive.

No food is junk.
Yes an apple is nutritionally better than a ho ho.
But everything in moderation will make for a happier you.

The fact you're in tears over this is not a good sign.
And you might benefit from talking to a counselor

Agreed.

Okay, so read through all the comments, glad you're feeling better. I was going to take a peek at your food diary to see what constituted a bad day in what you are doing, but your profile is private (that's okay, mine is too) so I'm going to base this on my own experiences and offer my point of view:
So let's reflect... when you're ready (you said you're getting to your mad at yourself stage and this is good for you, either at this stage or at the point you can look over things with a clear head..... my mad at myself stage is not always a good stage for me to look at stuff like this, I have to get to determination before I can be clear) look back at what you think you did wrong and ask yourself why you think it was wrong... it may not be that wrong at all. For example:
You look and say I ruined my diet because I ate {fill in food you feel was wrong}. Was it wrong because your diet says you can't eat it (maybe you're being too restrictive, this for me is where I fail, if I tell myself I can't have it, then I want it more, and I'll eat more and beat myself up because I did eat it)? If yes, maybe you need to rethink your diet and find something that works that's a little less restrictive Was it wrong simply because you ate too much of it? As a bunch of people said here, moderation with favorite foods is a big key, think about weighing and measuring, or next time cut what you have in half, eat that half and know that if you want the other half, you can have it... do you really want it? Maybe, maybe not, depending on how you feel at that point you can decide and then be clear on how to handle it (ie next meal will be back on my food plan so I can get right back to where I should be, I worked out an extra 20 minutes because I knew I was going to do this, someone's organizing a game of kickball, I can burn off those extra calories if I join in, let me go grab my kickball shoes!) Was it wrong because you we're bored and wouldn't have eaten it if you'd had something else to occupy yourself? If it's this, have a plan to occupy yourself when you get to this point... I give myself a manicure (can't touch anything for at least an hour or I'll mess it up) and if you still want it after that, have a small amount. Or if you're in a craving mode, set a date that you can have it (and I don't mean a far away date). My give in to cravings day is Friday, so if there is something that I'm really craving, if I still want it on Friday, then I can have it on Friday, if I don't want it on Friday then I don't have to have it, I have something else (I have Friday's as my eat out for lunch day, treat day, or whatever you want to call it, but you can use whatever day works for you.... I find that by Friday, I usually don't want whatever I was craving)
Just keep going, one foot in front of the other and soon you'll be where you want to go, if you mess up at one meal, don't let it ruin the rest of your day, just get back on track for the next time you eat.

Whats done is done ... one day of eating won't mess up your diet.. It takes burning 3500 calories in order to lose a LB and it takes the same to gain a LB so while you may have eaten junk and consumed more calories that you planned.. don't let it get you down, you most likely didn't eat enough to gain a LB and everyday is a new start .. so whats done is in the past just look forward to the upcoming days!

I used to do the same thing... Now I give myself a little treat every few days.. and it really does help with the cravings and the days of eating anything and everything I see.

Good Luck and Don't beat yourself up over this

its natural to binge once and a while. I had this issue the other night i was so proud i had eaten so well and then 1am hit and Idk what came over me, i added a good 600 calories in 5 mins. So the next day i dusted myself off, so to speak, i decided to make myself feel better i would knock off a couple hundred calories from what i normally eat and add on another 20-30 mins to my work out. And that is what I did yesterday and will be doing again today and tomorrow i will resume back to normal. Remember one bad meal will not hurt you.
