hi elana,
i'm sorry to hear you're feeling alone. has the feeling (it looks like it was this morning) passed, or is it still lingering around? i'm not sure what to say that will help, but i would comment that perhaps you've put up walls to protect yourself, that are leaving you also feeling closed off from others.
for instance, i think you put a lot into PC with reading the posts and providing thoughtful, and often helpful, replies, yet i noticed that your profile won't allow for private messages. there was a point at which you had posted something in response to a thread that i started, and what you said was helpful to me and i wanted to send you an email to say thanks - but i couldn't. just mentioning it because i wonder if there are other people that have been in the same boat, that are trying to reach out to you - but can't.
at any rate, not trying to convince you to change your privacy settings or anything (not at all), just commenting that maybe you're feeling alone because it's safer than feeling close to others.
if i'm way off the mark, just ignore, but please accept a hug
