My day got ruined.

I was having such a great day, until this lady and her daughter gave me a nasty look that completely messed up my day. I had tried on some spanx with a dress so when I come out of the dressing room (already disappointed because I needed a smaller size in spanx so it would hold me in) and this lady and her daughter both scan my body and what I'm holding and make a disgusted face. I walked out of there fast, and angry as ever. I know I shouldn't let things like these get to me, but I can't help it sometimes. I usually just ignore them but this time I couldn't take it anymore. I hate to have to go through this. I'm a size 18/20, I'm already insecure as it is. I know if I dont like myself, I should make a change, it just upsets me how people can be so cruel. If you're disgusted by me, stop looking at me.
