I understand you don't want to use homeschooling as an excuse for her not to attend middle school but don't rule it out as an option. Homeschoolers do NOT, as my husband will attest to, stay home all the time and never interact with others. We homeschool. In a typical month we are away from home: 3 Fridays for Co-Op classes, 1 Friday for a field trip (yes, a field trip every month), 1 Monday for an Earth Science class, every Thursday for Japanese, Violin lesson, and Orchestra. Other families that we know are away from home for team sports through the local Recreation Department, gymnastics, Karate, dance, Boy Scouts, Girl Scouts, etc. My son participated in the local Homeschool Science Fair and went on to Regionals (which is for public, private, etc. schools). Another student we know went on to the state level for History (I think) Fair of some kind.
A child does not have to go to school to have a social aspect to their lives.
Since you are praying, listen hard to the answer. It might be homeschooling or it might be being there to listen to and support your daughter daily when she comes home from school (which might also lead to homeschooling or might lead her to a wonderful year in middle school). Good luck and let us know what happens.
