Definitely a struggle here.
I've always been "weird" along with fat (although to varying degrees) and even though I know from a logical perspective that plenty of people find me attractive, and even though I can mask my weirdness well, when needed... it triggers a suspicion in me when attraction to me is acknowledged. Like I'm waiting for the part where it's just a cruel joke. Too much bullying and too few friends during my formative years has had lasting impact.
Rapidly gaining and losing weight over the past several years has also left me a little lost sometimes when it comes to literal self-image as well: I have so many different sized clothes, because I kind of never really know where my body is at anymore & don't trust it to stay stable.
