I must be a freak. I'll call anyone.

But I admit it was weird and awkward those first few times.

Maybe you'd feel better if you had a bit of a script to follow? Roleplay it with friends? I dunno.

But, if you're telling them you'll call, freezing up on the phone call, and then having a hard time even responding to e-mail when they ask why you haven't called, it sounds more like some variation of mild social anxiety.
