4 inch heels!!

I'm going on a date next weekend and I ended up buying some heels today that I totally loved. Problem is that they are 4 inches tall! I've never ever walked in heels that high. I tried them on for a little bit and my feet were red killing me. My pinky toe kinda sticks, not completely but it's really squished in there (they are pointy heels, thin heel). Is there any way I can actually wear these heels or should I return them? I have almost no experience walking in heels. 😭😭😭
