Thanks for your reply.

I am of course going to give proper notice and not disappear but might give my boss a heads up warning why I want to see her first – I won’t be working for the next 4 weeks as my contract states I only work school term times so I’ll need to make a trip in if I’m going to resign and I’d rather her be aware first than have it be a shock.

I just can’t get over this guilty feeling and I’m going to feel worse if I need to work a bit of my notice period.
