I'm not much for being alone either - and that's ok b/c it's virtually impossible when you have kids. Just remember that once you have kids, there is NO going back. So unless you're willing to give up your freedom to do and plan as you please, I would not advise kids. Brad and I love our kids dearly and wouldn't trade them for the world, but it is SOOO much work to do anything - even just going to the grocery store. I often skip going to the store b/c I don't want to drag two kids with me.
That being said, kids do bring so much light and joy to your world that aren't produced by anything else. Their smiles, their hugs, their laughter... the laughter is the best, with hugs coming in a close second. Their laughter makes me want to hug them. lol
Anyhow, I hope you are feeling better soon. I am a grumpy, unhappy, crabass when my sleep is disrupted.
