Home Decor Challenged. Help.

Is there like an app, other than Pinterest, that would help me decorate my walls? My living room is bare. I find I usually hate my decor choices later on and I wish I was good at this kind of stuff. I LOVE buying home decor and I have so much. Still in boxes, because I can’t figure it out!!

Does this frustrate anyone else? I have friends that always have perfect themes going in their homes and I’d literally pay someone for their expertise lol.
