How to get over first contact?

I am a pretty outgoing person and not shy at all but my “talking stages” with people I’m interested in usually start over text and immediately the thought of seeing and going up to the person and talking to them is an impossible task that would give me an anxiety attack (it wouldn’t). Also due to this, my over-the-phone talking stages last way too long. How early should I ask to meet the person and how to get over the fear of it. Also how early into talking to them over them phone should I ask to meet them?
