Is fat really the worst thing a human being can be? Is fat worse than vindictive, jealous, shallow, vain, boring, evil, or cruel? Not to me."
- J. K. Rowling
The size of your body says nothing about who you really are, or what your behaviors are, or whether you are worthy of love and affection. If anyone says otherwise, there are two possible reasons: One, they are a bully. Two, they are trying to sell you something. Sometimes, it's both simultaneously.
Don't assume that people dislike you. You are not a mind reader.
Don't try to predict what other people will do or say. You are not a fortune teller.
