Is it normal i am so heavily insecure with myself?

Chances are they're just jealous that they can't have proportions as small as yours, so ignore those idiots.

The people who give you shit about the size, or lack thereof, of your breasts and buttocks are basically just raging assholes! I know it's easier said than done, but try to ignore the and not respond to their stupid noise. People like the one's you're describing are very insignificant in the big picture. They're just basically walking turds.

I'm sure you have other qualities!

There are plenty of guys that think big butts and big boobs are super unattractive too, you know.
You are just fine as you are and there are certainly a lot of guys out there who think your body type is very attractive, so honestly you've nothing to be insecure about at all.

You haven't given enough information for anyone to try and figure out what might be wrong. Tell us about yourself.

I don't have a big butt or boobs either who cares?

Lots of guys like petite girls. Personally, I prefer them.

My boobs are big lol and my mom says I have a big butt. I don't really like myself but I guess it will get better. I'm super insecure and it sounds like I'm the exact opposite of you.

Its not normal you sould see that your beutefulll dont lissen to mean people.
