No confidence

So I've always dealt with not having any self esteem and no confidence blablabla. But since becoming pregnant (I'm 14w) it's got even worse, not fitting into clothes, I cant afford new clothes, my skins horrible, my hairs always greasy, I feel to sick to do anything so I never put makeup on or look half decent anymore and it's really getting me down. I don't know what to do. Has anyone felt this way and have any tips to help overcome it?

Note I wore makeup and got dressed up a few days ago for a cinema date with the other half but it didn't help.
