Meghan, I can relate completely to feeling alone and scared. It's normal as your H who is supposed to be there is not you person anymore. I don't mean it as he is the only one who can support you emotionally but at least for me, I felt I lost 3 people (my best friend, my lover and husband) when my H said he wanted a D. It will get better eventually as you get stronger. (Hugs)
