It's hard to get used to living alone after being with someone for a long time...it was hard for me after my husband and I separated. But I also found a lot of peace, and I had a chance to start learning how to comfort myself and to learn new coping strategies, so in the end I grew a lot as a person. The online support isn't exactly the same, but we are here for you.

From the movie The Hours: "If I were thinking clearly, Leonard, I would tell you that I wrestle alone in the dark, in the deep dark, and that only I can know. Only I can understand my condition. You live with the threat, you tell me you live with the threat of my extinction. Leonard, I live with it too."
