How did you find your self worth?

I have a major confidence problem and am struggling to find my self worth.

I was brought up believing that I will never amount to anything.

Even as an adult I've heard 'what makes you think you deserve better '.

I've always been a good hearted person, I'm extremely empathetic, compassionate and kind.

But I have come to realise that I've made myself a door mat. People walk all over me.

Nobody respects me.

I seem to be a magnet for negativity.

It's become even worse since I've been unemployed and disabled.

I feel like I bring nothing to the table and I'm completely worthless.

I have to rely on someone else just to stay alive.

I'm desperately trying to come up with a solution so I can earn an income and at least contribute. I think it will help my confidence greatly, but it's a major challenge that I've not been successful with to date, and it's been years.

Question for you all, how did you find your self worth and confidence?
