I give up on becoming confident because i'm ugly

With that self defeating attitude "I give up on becoming confident because I'm ugly" You will always be and remain UGLY

Try getting your weight down to a reasonable level that's most likely your problem. You like to stuff your face.

Haven't you ever seen butt ugly guys with lovely women and vice versa? Burn scared, disabilities and obese people with perfectly lovely partners? Why do you think that is? Could it be that what's on the outside doesn't really mean shit when it comes down to who you really are?
If you think you are ugly now, imagine yourself in 50 years! Stop wasting your time crying about what's not important and concentrate on what is.

You can be confident in many things.

Let's say the worlds greatest neurosurgeon was ugly. Should they avoid being confident in themselves, their achievements or skill as the worlds leading neurosurgeon? Hell no.

So you don't have great looks, neither do I. But I am confident. I _act_ confident and attractive, I get far more than average levels of attention.

Be confident in who you are.

In whose view are you ugly? Societies? Well, society is one jacked up place because apparently if you're not a model you're not worth crap. THATS WRONG. I think that every single person it's got beauty on the inside even if it doesn't seem so on the outside. Don't change yourself because the media have said that if you aren't jaw-dropping, fuck-me-now hot then you're worthless, because that's not right. Keep your head up and remember that you're not ugly.

If you're ugly then you want to compensate for it with confidence.
