My best friend moved back home almost a month ago. We only knew each other for a short time from work, about a year but in that year we became extremely close. She is only one of three people that I've about my mental health issues. I truly do have a deep love for her, something I've only ever felt for my daughter and wife.

I'm having a hard time dealing with her leaving. It probably wouldn't be so bad if she was closer and had reasons to come back, but she's almost 1000 miles away and all her family is where she is. I usually like my job, but since she left I don't look forward to going there anymore. Just when I think I'm starting to accept it I relapse. Just this morning I was sitting at the computer drinking my coffee and I totally broke down and started crying. All day at work I had to fight the urge to just start sobbing and had to go to the bathroom multiple times to compose myself.

I know the grieving period is different for everyone, but how long is this going to last? Why can't I get her out of my head? I can't concentrate on anything lately and I'm afraid it's going to start showing at home and work.
