Who in your childhood was good and loving to you? Your Mom or your Dad (or both)? Who wasn't such a good parent? (Few people have ideal parents, these days. Unfortunately. They may try their best, but no one is perfect.)
Take the time today to speak with the parent you feel closer to, and talk about what it was like when you were first born. Tell them you've been thinking a lot about it recently. Ask them about your eating patterns. Were you breast or bottle fed? Did they hold you? Did they enjoy being parents? What were the challenges? What were they especially good at, and what could they have done better?
What was your relationship with food while growing up? What did eating mean? What events took place around it?
Having a conversation like this with a childhood care-provider or parent can illuminate a lot of details about why you're struggling with an overweight problem today. (If your parents aren't available or are unwilling, talk to an older sibling or relative.) This will be highly productive material.
