I can't buy myself things

does anyone else feel bad when they want to buy themselves stuff lol. I'm 31 weeks pregnant and none of my clothes fit me im so uncomfortable to leave my house because all I can wear is my husband's clothes and look like a hobo cause they are huge lol but anyway I have some extra money and I went to Ross but I couldn't let myself buy the cart full I had for me I feel like I should buy my daughter more and this baby stuff before me even though they have everything needed. ugh the struggle
