lonely: I broke up with my boyfriend a month ago.  It was hard but he just wasn't right for me.  The biggest problem I have now is that I feel so isolated and lonely without him.

It was the right thing to do. Getting used to not having someone around is going to take some time.

Yeah, I definitely don't want to get back together just because I miss having someone but its definitely hard.  I'm struggling to find things to do or get out with friends.

It will take time, but I'm sure you'll be okay.
