Leaving work / moving on

Hi All,

I have been in my jobs for maybe 4 months - I have previously posted as to how it isn't really a job and I sit there all day with nothing to do.

I explained to them I am anxious and have been signed off for nearly a month. I am bored and want to return to work but I don't feel returning to that job will help me at all. 

I have had a few interviews etc and hoping to have a job offer this week. 

If I quit do you think I will have to work my notice?  - My GP has been quite understanding that the job itself is the current cause/ trigger for my anxiety.  

I was doing quite well and recovering steadily up until taking on this role. 

Any advice on how I can quit what to say to my boss. 

I don't want to have been on sick leave for a month quit and him quickly receive a reference request.

I have explained to him the job itself is a source of anxiety and I was considering quitting about 2 weeks ago.

I have also said that I dislike living and working in the town I currently live and want to move (due to crazy Ex's having followed me and moved in just a few minutes away) 

Any help/advise/support kind words appreciated. 

Thanks

Grace
