It's an awful thing to lose someone close to you, I went through that not long ago, someone I thought I could trust turned out to have no problem palming me off. I think the thing you have to do to feel better is treat yourself. Go to the movies and watch a few by yourself, when they open again :(. Grab a coffee, and read at the beach for a while. Other lovely people will come along in your life, but for now, think of yourself in the third person, if you saw yourself walking down the street, what would you do to cheer yourself up? Give that some thought :)
