It's all relative Doilook. I think 5ft 6 is quite small! I have a photo of me and 2 friends; one is 5ft and about a size 4-6 one is 5ft 5 and a size 8-10 and I am 5ft 10 and a size 12-14. The smaller friend looks like a normal sized person, the medium friend looks big and I look like a genetic monster. I am in proportion so any picture of me alone looks fine but when I am put alongside any other woman or man under 6ft I look freakishly large.
I spent years trying to diet and make myself smaller all over. Comparing myself unfavourably to other women and it was miserable. The weird thing is when i'm alone and naked I feel great, it's just when I try to fit into clothes which are not suited to me or I stand near other people that I feel like the hulk.
I have had years of nasty comments, mostly from men, which at first I internalised and tried to change myself. But then I started to realise the comments were a feminist issue. they were said in a disgusted and entitled way that I wasn't smaller. That I was taking up more space than them. I was upsetting the power dynamic they enjoyed. They were entitled to feel like the strongest and biggest and I was an offence to them. Of course there were also many men who fetishized it. Wanted me to dominate them etc. Kept going on about what an amazon I am etc. They were almost as bad. Making me feel 'other'.
Anyway, I stopped comparing myself in a negative way and when I had children I really started to love my body - especially my pregnancy body. I love how strong it is and what it can do. I haven't hated my body for the last 10 years and I really regret wasting my 20s worrying about things I can't change.
