im totally an emotional eater...the good the bad and the ugly. i still struggle with it now, although i think for now i have it under control as my desire to loose weight is stronger than my need to eat. Its something i try not to beat myself up about becasue that just seems to make things worse. I know what you are going through with your dad as i lost my mum to cancer 7 years this xmas eve. it was one of the hardest thing to go through and food was how i conforted myself.
i got through by getting help and then helping myself, by writting down what i was scared of, what i felt and thought, all the chaos and not judged myself for it and then burned it all so i could let go of it. Since then you know,i still loose control, still cave in but i give myself permission to do so and then somehow i can pull out of it. Over the last year or so its been getting the better of me, as i adjust to a new relationship and my health issues and money, all the usual things. i just waited till i was ready, till my body was ready to say na, ive had enough and want something healithier. Now i give myself something else to focus on to comfort myself, a bath,(were on tank water so this is a real treat) or buy myself a magazine ive wanted to read or a that plant ive had my eye on and work in my garden, it keeps me sane and helps me to focus my attention elsewhere.
Hope that helps somewhat
