I know all too well what you are saying. I don't like to go out, because it's a reminder to me that I'm a failure in life. But today I didn't eat all day long and wasn't in the mood and didn't have the energy to prepare anything, so, I went out to buy a Pizza after 10:00 pm, and in my way home I saw a couple walking. They weren't laughing. Just saw them from a distance walking together, and a negative feeling hit my stomach. I feel bad saying this, but I envied them hearing they were talking to each others!!
