How to tell mum EDIT

So I'm pregnant and I need to tell my mum. I'm 22 by the way! Im just a little scared. I'm single and wasn't trying for a baby. I'm just worried about how she's going to feel about it because of the fact I'm single... I'm currently living in work accomodation but during November-feburary I normally live with my mum but obviously this year I won't be able too soon worried she'll say something about that too...

So basically Im too far away from her at the moment to tell her on person so I need a nice way to message her (she won't answer phone calls) to tell her I'm pregnant, it wasn't planned, Im single but I'm actually really happy and excited about it!

EDIT: She has anxiety and won't answer phone calls. Nothing I can do will change that.
