I feel like I'm developing depression and loneliness being at home all day by myself Noone to really talk to and no car (live at my husbands parents.) I finally was able to go out for a couple hours with my best friend in high school and she could notice something is off, none of us know what it is but I think this is what's causing it... my husband works all day then night school then sleeps... I just want my little boy to get here already so I can have someone to love, play with and be with me all day to keep me company. I don't know what to do and feel like I'm gonna lose my sanity and break down and cry.... sometimes I find myself talking to my baby boy after we read a book or sing songs
