It's been hard being alone...

I took today off bc I've had a busy week and wanted to get things done, clean house, study, laundry, you know, just get ahead. But I find when I'm alone I get lonely and sad. All the pregnancy emotions come out and I seem to not get anything done. I typically like being alone and love setting up projects for myself. But I'm finding that I'm craving human interaction while I'm pregnant, which is great, but I want to get things done, too. I've noticed, at 20 weeks, I get tired really easily. pregnancy is definitely one big roller coaster, some ups and some downs. So now I just need to figure it how to be alone, and be happy and motivated... Anyone else felt this way?
