Been a sahm for 16 years, not always through choice, but that's another story.
I start a part time job in Monday, only in a shop, albeit a very high high end one.
I had no idea how my confidence has plummeted, I am terrified that people won't like me, that I won't pick things up quickly enough.
I feel massively out of my comfort zone, I have barely eaten for 3 days and am so nervous i am nearly in tears 
I don't know what the hell is wrong with me.
