How can I talk better with females?

Hello everyone, I'm an 18 years old guy. I have been homeschooled for last 2 years and had no female interaction whatsoever. Even before that I had negligible amount of female interaction. Mostly the only female interactions I have are with my mother and sisters.

Whenever I see a women trying to talk to me, I get very anxious and forget about talking even if I see them nearby me, I feel very weird. I also live in a country where it's not normal to have casual talks with women, so that made me like this as well.

What's the best way I can normalize myself to talk and interact with women?
