It sounds like a pretty normal reaction to the situation. You're displaced and left alone... surely there's more to life. I know when I was in a similar frame of mind I had to get away and busy myself with some creative effort. Maybe there's a group activity you could attend on occasion to meet a few friends? Trust me I know the love for a child is awesome but you also need some friends your age to mingle with. Just my lil offering... best wishes to you.
