Body Dysmorphia Disorder (BDD)

Hey everyone, if you read this all the way then thanks. This may be a trigger for some so let me put that out there.

I haven't been officially diagnosed but I'm pretty certain I have BDD. I haven't told anyone because I'm sure they'll think I'm just seeking attention or fishing for compliments, not to mention I feel pretty pathetic for it. It's so strange because although I can think logically and rationally, the feelings won't go away. Some days I'm fine but most days I feel like absolute crap. I absolutely despise the way I look, body, face and all. I constantly compare myself to other girls, whether online or in real life and that makes me feel like shit. The rational side of me says I'm beautiful the way I am, I'm healthy, I can't compare to models because photos can be fake and their bodies could have had surgery etc but it's like the BDD won't listen and I constantly stare in the mirror, measure myself, pick out every single flaw and what I would want to change and other things that I'm too ashamed to even admit.

It takes up a lot of my time that I should be spending looking after my house and kids, and it depresses me which is not nice for my husband because he comes home to a miserable wife and he doesn't even know why. I know I need help because it is affecting my life and the lives of those whom I love dearly. I can't brush it off anymore and tell myself that I'll deal with it without help. I don't know where to go for help, does anyone have any advice? I feel like I really need someone to talk to but I'm not sure where to go for that. I'm situated in the UK, if anyone could advise me on how to go about this I'd really really appreciate it, thanks in advance!
