I did the LC thing while living in the same small town as my mom years ago. It definitely gets easier!
It was pretty difficult for me at first because I had (and still have) very severe social anxiety, and my mom was the only one I'd really talk to. I was difficult to go LC because I'd get bored and want to talk to someone, and my mom was my connection to the rest of the family and close family friends.
Eventually, I made some friends online and I'd post in message boards. I made 2 "real life" friends, and one friend was close enough that I could tell her pretty much everything that was going on. She told me that when she first met my mom, she felt that something was 'off', so I knew she was a keeper.

Very few people are able to see *through* my mom. I also got started in therapy with a really good trauma therapist, and that was another way for me to interact with others. I got started in school and participated in class, joined a few student groups, and w/ all of this interaction, was able to really put some distance between my mom and me.
It's been about 11 years of V,VLC, and I'm so much better off. However, I will admit that everytime I talk to her (twice a year, my birthday and hers are 6 months apart), I do get my hopes up. I
know that she won't change. I know that I have to watch what I say (to avoid having anything twisted around when my mom inevitably repeats it to others), but I'm always genuinely happy to hear from her. I also know that I have to take everything she says with a grain of salt, because she makes up random stories (huge lies, and tiny lies). I don't know why I'm so drawn to her.
She is very charismatic and good at telling people what they want to hear. She knows how much I love to help people, and she plays on that a lot.
Sorry, I just went off on a tangent with all that! Distraction helps a lot, though. As does widening your social circle. And if there are friends or family members you usually associate with when you're with your mom, try to get to know them on your own.
