I really need some help ladies.. I'm not sure why but lately I've been very very sad. I have no reason to be since my boyfriend and I are finally moving into a decent apartment that is close to my family and far, far away from his. Also I've got opportunities for jobs and school opening for the program I want to attend yet I'm still just feeling awful. I have been crying about things no one would cry about..maybe I'm stressed? I don't know why I would be, but I'm just so uninterested in everything. I can't sleep, I barely eat. Could I have some type of pregnancy depression?
