See, this is what we introverts have to deal with. It's not something WRONG with me. It's just the way I am. I don't like to have people over. I asked if there were people who could relate. If you can't relate please don't say there's something wrong with me. It's like telling someone who doesn't like chocolate that there's really something wrong with them and they should like chocolate, or like telling someone they should really like "Call Me Maybe" or Beethoven's Fifth because they're just great. We just don't all like the same things. I just don't like people in my space. That doesn't make me mentally ill. I am extremely familiar with anxiety and this isn't it.
Edited to clarify and add: Here's a great TED Talk about Introverts: I could so relate!! http://www.thepowerofintroverts.com/about-the-book/ (scroll down a bit).
((HUGS)) mama. I love this ted talk and share it with my friends because it is so true.
I am a total introvert, as is my DH and my kids to some degree... and we haven't really had sleep overs. We just like our space and don't like to be "on" in our space to entertain. I know exactly how you feel and no, you don't need therapy.
Just find other things to do... maybe put a tent up in the backyard and have the kids "camp" in the yard during the summer...
One of my kids hates sleep overs and always calls to be picked up...
We've been doing trips for birthdays and that is fun. Find a hotel with a pool and it is extra fun for the kids... then you don't have to worry about hosting in your space. Maybe bring one friend for the birthday child? We don't have TV so just even staying in a hotel overnight is fun for us... with the TV and stuff... there is a hotel here in town that has a movie theater and indoor pool... it is a little extra for the room but worth the $ to not have the stress!
