Are you self-Confident?

Because I believed the things that others said about me and now I can't think in a different way

You have to come up with the way you see urself. And learn to not care about what others say.

I try, hope it'll get better. Thank you :)

Why not?

My ways of communication isn't so pleasant, as for looks I would feel it's not normal

Just be yourself and learn to love your imperfections. Ur imperfections is apart of what makes you, you! Never compare your self to others. And about looks I'm pretty sure you are as much Cute as anyone else.
