Baby shower advice !??

Okay so my mother and grandmother are planning a baby shower for me... However, I honestly don't care for one & I literally have no one to invite and I'll feel really uncomfortable st my own shower if I just invited a bunch of coworkers that I'm not really familiar with just for the heck of it ? & to top it off there's only about 5 people that will definitely be there if I do have one, I don't know what to say or do...  HELP PLZ!
