Honeybee79 so sorry you feel so stressed about this but totally echo mollycuddles and foreverondiet 'stop with the self loathing'.
You are an amazing mummy and you have grown a baby!
Don't avoid mirrors, love yourself and you will be better able to pass on a healthy self image to your lovely baby. If you are a bit bigger than you were, do not worry, you can control it and change with time, be gentle on yourself. You want to be healthy again, rightly so, but just be nice to yourself along the route - you will be more likely to stick with it and will arrive in better shape all round when you get there (physically and emotionally).
Now you are having to have a more 'still' time of it at home and not getting the exercise you are used to - so of course you are finding it hard to burn up the calories, especially if you are eating more due to boredom. I know all about that as I have real problems with food to do with eating because of boredom and all kinds of things. I have started doing 'mindful eating', eating slowly, stopping when full, and if I fancy a snack or some food I am trying to question myself, do I really need extra food. Is it healthy, good for me? I can have nice treats sometimes but do I really want it. Do I want that chocolate bar/biscuit whatever or is it that my daughter has taken a bite out of it and said she does not like it! So am I using my body as a bin by eating something I don't really need! Very unlikely your baby is offering you food but you know what I mean!
Try eating healthy food, sounds obvious but go for fruit and veg when you can, these will be filling but also give you lots of nutrients. I get bored eating apples etc so I slice them up thin like potato chips and carrot batons to crunch on!
I go walking (with friends and friend's dog).
I am thinking of doing a race for life

here
Race for life might be something to aim for - you can even walk it. If you are fit enough to do something like that maybe give it a go. Maybe a gentle post natal exercise DVD you can do at home? A walk with a friend once a week at a time when DH can have some time with baby. My DH looks after DD one night a week so I and a couple of girls can go for a walk. We chat, get fresh air and amazingly we have been very lucky, in almost a year it has hardly ever rained on our walk night!
Anyway, try all these ideas and the others mentioned but do stop being cross with yourself, you can be in control and just keep an eye on your emotions and how you are feeling. If you are worried, talk to someone in real life.
Best wishes.
