I don't understand

Over that past few days I haven't quite been able to tell if some of these people were lying or telling to truth...
'You look like a cute puppy when you laugh.' Wtf?
'I would describe you as unnecessarily cruel.' Believable
'Sometimes you look like you just don't care so you remind me of a robot.' Fair Enough
After saying I wanted to buy some panda onesies, 'You would be a fat panda.' This one just pisses me off but at the time I could only think, if I'm fat then what are you? A whale? I know its mean but she weighs 3x me and is only a head taller. I can't help believe her though, I am fat.
'Your so fat.' From my mom and brother. Great family support.
