Pregnant and depressed

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.
