How many friends do you have?

My SO is a very well liked person and has a large group of friends, I on the other hand have 1 friend that has been a friend for years, (we don't see each other very often). SO's friends have been saying frequently how I should have a baby shower (I brush it off as I already have a 6 yr old and dont feel it's appropriate to have one for a second child) the real reason is I actually have no one I could invite. SO has 6 groomsmen picked out (there would be 10 if I let him) and I have 1 person I could have as a bridesmaid. I know it probably sounds like I'm being very melodramatic, and it could be the pregnancy hormones but it is really affecting me. I feel like such a loser.
