Please help me

So I’m an 18 year old female and I’m 5 foot 3. My mums is constantly telling me I’m anorexic and look withdrawn and bad undereyes. This is worrying me as I don’t see it at all. I see the undereyes but that’s because I’m always tried. I weight 7 stone 4.6. I’m worried I have body dysmorphia ( where you don’t realise you look skinny or fat) and I’ve been crying for ages I’m worried. Am I anorexic?

^ sorry I don’t know why the photo is doing that x

Update: she’s making me go see a doctor
