Why do I look so ugly in Photos? Is it me?

How come I look in the mirror, i look alright to myself, but in photos i look terrible! Seriously, Im afraid to take photos because i look so ugly. Is it like a mind thing? Or do i just take bad pictures? Thanks
Update: I Tried the thing with holding the camera far away and zooming in and it looks much better!! These Are all good answers im sorry i can only pick one best
