Could have been me that has written this and I'm glad I came across this thread.
Unless I know people in a bigger group well, I just have no clue what to talk about and guess that people just find me really really boring. I understand, somewhat, I often find myself really boring, I have zero interesting hobbies like everyone else seems to have and share. I'm rather shy and don't really know what to say. I told a guy from work that I'm pretty shy and he said I wouldn't come across as shy, but I confessed to him that at work, I don't have a problem, as I have a "subject" (work), so I can get into a conversation. It's really just a masquerade.
I'm also not "one of the girls", never really have been. I tend to get on well with men though, and always have, which I don't mind. But I'd like a "girl friend", someone I could essentially have Tattle chats with but in real life.
Last year around New Years I felt so lonely that I made a resolution to sign up for a friend board (women only) and I indeed got talking with a girl from my town, but our chats are very irregular and we so far never have met up.
Both my boyfriend and I work from home and, honestly, if not for each other, it could be days until we have human contact. I'm quite certain that we'll be one of those old couples one day that call the police out of loneliness or someone else calls them because there's an odd smell.
