Why is being complimented so difficult


I hate that I have two ways of honking and they both work at the same time. One part of me believing that I am fat and another thinking I am thin. People don’t seem to understand that telling me I am pretty or slim doesn’t help anything it doesn’t make me feel better. It makes me think that they are just saying it or they are mocking or taking the piss 🙁 I just wanna be able to take a compliment not question it just be able to accept it and not allow my mind to turn it automatically into a negative remark 🙁
