This really resonates with me, too, OP. Growing up I always had best friends, but things went haywire when I went to high school due to bullying and a sexual assault. I turned to alcohol as a result.
I did have an amazing group of close friends at uni, but I was a nightmare to live with, and they walked away - looking back it was understandable, but at the time I felt massively betrayed, and I spent the time until I got sober trying to find replacements for them.
Since I got sober (and this was fifteen years ago), I've never been able to properly let anybody get close to me. I have a lot of acquaintances, but hardly any of them know about my past, because I feel I have to keep it all a secret. I'm also a writer, and I write a lot about my drinking days etc, so I feel I have to keep that a secret as well.
I'd love to have a best friend. I'll never be somebody who's happy having no friends, like some people.
I love writing, literature, politics, The Simpsons, drinking coffee and buying books and makeup. I don't suppose anybody here lives in Norfolk/Suffolk, do they?
