I'm Insecure

I'm one those girls who's very insecure and has trouble loving herself, I may seem happy on the outside but in the inside I'm struggling with self hate issues. I think I'm so fat, there are skinnier & prettier girls out there, I'm just a waste of space. I know I shouldn't think these things , but I do, a lot.
Some people can probably relate to this post, yes, everyone is beautiful, but it's going to take awhile for me to believe that about myself.
