Just a bit of background information firstly, before I delve into the inner workings of my mind. I am 24, size 12 bottom and 10 top (think standard pear shape). I am 5ft 8. My BMI is just about too high, at 25; I carry most of my weight on my thighs/hips, so not much abdominal/visceral fat I would think. I have a fairly active job and love walking – I’d say my step count is over 15k 4/7 days a week. I am isolating currently due to COVID however when we can, I intend to start going to fun gym classes a couple of times a week with MIL. I don’t over eat – mostly under 1700 calories per day.
I have a bit of a complex history with food – from age 14 to about 20 I was more like an 8 bottom and 8/sometimes 6 top, however this was as the result of fairly severe restriction. At worst I was only eating one meal (eg. Chicken stir fry, chicken and chargrilled veg.. anything with chicken) and one small snack (eg. Freddo) per day. Also quite obsessed with ‘earning my calories’– never formally diagnosed with an eating disorder. Long history of clinical anxiety and (mild) depression.
DM has policed my weight since I was a teenager and I feel her attitude is one of the reasons I am so conflicted – some of you may possibly remember a thread I wrote months ago surrounding this. She is of the opinion that I look much better smaller, even though I have made it clear that I was only ever skinny through being quite ill and troubled. I catch my grandma asking her in whispered voices whether I’ve lost any weight yet. DM tells me ‘not to be eating too much’ when I stay with my boyfriend over the weekend. Basically with the way they speak, it is as though I am grossly overweight… and they don’t make much of a secret about it.
My problem is that, although I am aware their behaviour is borderline abusive, I find it very difficult to get out of the engrained mindset that I need to shrink myself because it has been so long that it has been drummed into me. My boyfriend’s and his family are the opposite of mine – they worry when they see any restriction from me and actively discourage it. These conflicting forces mean I spend my life in a cycle of ‘oh my god I am enormous, I need to starve myself’ and ‘this is what I look like now, I need to accept it’. Just lately I am veering more towards one meal a day again 
I do STRONGLY prefer my body when I am smaller than I am currently and obviously according to BMI I could do with losing a few kg’s. However the only thing that has changed for me is that I am happier, more stable and now (mostly) eat like a normal human being. I don’t stuff myself with crap, I don’t eat carbs with every meal and I eat LESS than the daily recommended calories for a woman. I know I could lose weight, but I guess my question is should I focussing on that, if to do it I would have to compromise my recovery, and be hungry all the time? I don’t want to go back to obsessing and punishing myself but I feel trapped in this diet cycle.
Instead, should I be trying to learn to accept that this is what my body looks like now that I am healthier? That it’s normal not to look like I did when I was a teenager? And if so, do any of you have any books that you can recommend to me to help with this acceptance? Or should I be trying to lose some weight?
I am just struggling with this constant internal monologue and don't want to keep living like this
