Yes there are.
I personally would not recommend you jump into a full on milsim just yet. Get in some short walk on day skirmishes and "pick up games" and then work your way up to 6-8 hour day sims then get into the milsim thing.
There's lots of venues available to play at just wait until the summer. I can't speak for what the scene is out there but I do know there's tonnes of venues to play at which totally newbie friendly and have a good mix.
At the same time though, if you have a bad experience don't just quit, try a different venue/group and see where that takes you. I know that I don't like the way a certain group I've played with plays and that's fine, they do their thing and I do mine, it's just not my cup of tea. At the same time there's another group that I totally fit in with and I want to see them expand their ranks.
tl;dr just keep looking. Maybe don't dive in head first to a full on milsim but try it out and try a couple of daysims to get a taste.
