I'm sure you have probably already tried this but do you have any hobbies you enjoy? Do you enjoy gaming or RPGs? On meetup.com you can find people with similar interests to hang out with.

I had a good friend that was smothering me. I know she didn't mean to but I was her ONLY friend. So I got her signed up on meetup and now she barely has time for me she's met so many other people. She found that she adored playing Pathfinder and Magic the Gathering. Maybe there would be something on there that you would like as well.
