Feel like I’m not valid

So... umm. I feel like I can’t be a little with my partner because she’s a switch and well as 50x more skinny than me. I’m super fat. Know I’m fat. Been called fat at school. Been looked up and down by skinny bitches then given a dirty face. So I’m like super fat and a little taller than her and she’s like a SX is kids clothes and is like and inch shorter than me so I feel like maybe I just shouldn’t be a little even tho it something that really helps me out when stressed but now when I’m stressed and go into my little space I get depressed because I don’t feel valid because my caregivers doesn’t really care and can be a bottom herself and when a try to say things when she’s dominant like “what if blah blah blah” and then she get upset because she’s a switch and not a full dominant and makes me feel bad. And I just feel like I can be a little for all these reasons. And I could say a lot more but I don’t want to bore you. Sorry for being annoying if your read this far
