Lonely

I'm having one of those days where I feel overwhelmed with loneliness.  I've had a really busy week, but today is calmer.  Maybe I'm not good with calm? :)  Sometimes I wonder.  I was looking forward to things being calmer today, but now I don't feel so great.  Is that weird?  I think working from home really messes with me sometimes about this - sometimes I don't interact with anyone except my students (I'm a private math tutor) and, though I love my students, I need more adult interaction.  Other times, I crave the alone time.  I really make no sense on this!  How do you all balance your need for connection with your need for alone time?  I love my work and working for myself, so I don't want to get a different job.  Just not sure how to deal with the loneliness at times.
