Here's the truth
You have been through a dramatic life change in the past 7 years. You have gained weight. You can lost that weight
I'm wondering if you came onto a forum of strangers looking for the "brutal truth" because you want (sub consciously) to hear what a bad person you are for being overweight. How you are putting your life in danger and this someone makes you less than or less worthy of something. The sad truth of it is, whether or not people want to believe it, we eat to fill a need. Sometimes that's stress, sometimes it's comfort, sometimes its lack of time, sometimes it the only thing we can control in our lives, sometimes it's the only thing we can let go out of control in our lives. Very, very few people are "just greedy". It actually amazes me when I see people on MN come on and say "well I only ate because I was greedy and that's why I gained 6 stone". No, your greed was (whether you choose to accept this or not) a symptom of something else and if you do not deal with the "something else" then the weight will come back on. AND I am sure there will be people who argue with me and say "you don't me, you don't know I wasn't just greedy" You are right, I don't know you and if you want to flagellate yourself for gaining weight go ahead, I won't stop you.
OP you are not your weight, and you can change it.
Start small, as someone suggested earlier My Fitness Pal is excellent. or get a FITBIT or both and connect them. Keep an (honest) food diary for a week to see where it is you feel you're overeating. Maybe it's when your children are in bed and you then eat two days worth of calories as a reward because you've had a hard day ( no judgement btw......I have done this in the past!) Maybe you are grabbing bits all day and not eating a proper meal and those "bits" are adding up to 1000's or calories.
Whatever it is HERE is the truth. You are 29, you have 2 small children, you are young, you have MORE THAN LIKELY done nothing irreversible to your health yet. You can change, you are good enough, you are worthy of this weight loss and you absolutely can do it.
