im always feel insecure and comparing myself to others help?

Hello,

I dont know why im like this..

Im totally insecured specially to my nose.

It is flat and have low bridge nose

I dont know .. Im insecure I always put myself down.. I have low self esteem.

I feel ugly.. I compare myself to other girls,

Why they are more whiter,have a pointed nose,have more sexy body than me.. If i end up telling this thoughts to other people they will end up saying that im a lowlife scumbag that i doesnt appreciate their beautys..

I have a boyfriend.. Were dating for 1year and 2months. I feel insecured whenever i see his activities on social media like liking other girls picture who is beautiful than me.

He never failed to tell me everyday how beautiful i am despite of my flaws and he always assure me that he loves me that he will never replace me because he said that im the girl who is hard to find and he also said that he accept me for who i am .

But i cant stop overthink .. What if he met a better girl than me , who's more beautiful and perfect.

I never thought myself pretty.. I wish im those girls.. because girls who are beautiful,have a perfect body,famous are accepted in the society..

Im just a girl that is simple. I have scoliosis,acne on face and imperfect

I feel down and depressed..

I wish i was more beautiful so theres no need to compare myself to others.
