Baby necessities

Hi ya'll! So I'm almost 26 weeks and my baby shower is in about 4 weeks. I've been getting my registry together and since I'm a FTM I've had a hard time figuring out what I need. Mostly I've been doing research on mommy blogs/pinterest. A good friend of mine has been filing me in on all these things I need. Which I appreciate because I have no idea other than the basics. But now I'm kind of stressed out. There are so many things! And I'm worried that it's too expensive and people won't get any baby shower gifts. But she keeps saying these are things that are a must have. Honestly, the only reason I'm having a shower is to get things for the baby. That might sound mean but I'm just not a fan of events focused around me. I didn't even want a wedding when my husband and I got married. I would have just gone to city hall. The point of my long rambling post is that I'm so stressed about all this stuff. Some of it seems so unnecessary. I just don't know though. Part of me thinks that I should put less stuff. But I've also registered for gift cards. So maybe people will do that? And then I can pick and choose later. Goodness I just don't know. Clothes are probably the only thing we have a good amount of. That's because I've been buying clothes most of my pregnancy (in a variety of sizes). I kind of wish the shower was over with so I could figure out what I need and start planning to buy myself. Does anyone else feel this way? Or am I being a crazy person??
