sounds like that 1 person is more than 'just' somebody on the internet
i've known a friend of mine for about 7 years and i've never met her in real life yet she's the only one i'd trust with everything i tell her. i know that she's the person i can go to whenever i want. we could have conversations on a daily basis, but we could also easily not speak for months and get back in touch as if we were talking the day before that and still fully trust each other
fyi i'm in the same boat as you. i don't trust anyone around me, just that one friend
shouldn't downgrade that one person that you've got in your life to 'just' somebody bc sounds like that person is more than that
sometimes the right people can't be found in real life, in that case you'd be lucky enough to find that person on the internet
and who knows what will happen in life, you might even get to meet that one friend
friendships on the internet can be just as special as the ones you can possibly have in real life
