Baby shower (need to vent)

I've been planing my own baby shower since no one offered to throw it for me. My husband and i have been paying for everything (cake, candy, decorations, centerpieces, ect... I have two sisters and they have not offered to help at all buuut they always send pictures of things i "need" to get or they go to parties and i always get pictures saying "do this". It really gets to me because im doing this alone and they have all these "suggestions" but dont offer to help of do them for me and honestly it stresses me out so bad and gets me so emotional every time i get pictures of them saying to get a certain item.
