I'm too afraid to talk to women

My understanding of your question is that you struggle with anxiety when talking with women  

When you are talking to a woman, pick a topic you are comfortable with and focus on what they are saying.  Be mindful of any expectations you are placing on the conversation (are you thinking it is more than just a conversation, looking to define what the relationship could be).  If you find that you are trying to predict a relationship outcome, take a breath and refocus on the conversation.   Take one moment at a a time and stay in the present.  Often shyness comes from putting too much pressure on ourselves to turn every conversation into something "meaningful" rather than just enjoying the conversation.  Practice casual conversations with people you already know, take note how you feel and what is easy about them.   When you meet someone new, often times they also have some anxiety about starting a conversation, so start simple.  Stay away from "hot topics" like politics or religion.  Example:  if you are at a party you can ask how the other person knows the host and if they are enjoying the party. Commenting on the food is also an easy way to start.   It is also ok to be an observer for a bit before starting a conversation with someone.  

Take note of any thoughts and emotions you are experiencing before you go out. What are some of the beliefs associated with the activity?  Challenge negative beliefs by thinking about the times you were successful at talking to a woman.  Focus on what went well and the topics you found comfortable.  Think about what makes talking to men easy for you, pull from those skills.

Try what is called opposite action, if your thoughts are telling you that you won't have a successful or comfortable conversation, challenge them, take a deep breath and approach the person and say Hi.   Basically, do it anyway even if you don't believe you can.  It takes practice so be gentle with yourself and remember that most people struggle with starting a conversation.   

The anxiety is often associated with fear of being judged or rejected   Something to remember: how someone perceives us does not change who we are   Some people will like us and others will not, just be you and you will attract the right people for you.
