Hmm that's weird but I understand, the anxiety stems from the anticipation about their response right? haha you're not the only one that thinks that way. That's another excuse, if you didn't stutter it would be social anxiety? Then if not social anxiety, your not feeling up to it etc. Not to be a douche but excuses can be endless if you decide your not going to do something See I offered you a chance to have a skype conversation and you didn't say yes or no, you listed it among the things you wanted to do but couldn't, or is that wouldn't do? Life is seriously too short to be so anxious, if you just dive into situations without dwelling on them too much, they can go surprisingly well. Just give yourself a chance
