I work in mental health, I started my job in March but I hate it. I resigned and I have 6 weeks notice to work. I went off sick last week but I just don't want to go back, it's been hard and I dread it, feeling a horrible knot in my stomach and constantly thinking about work. Is there anyway I can just leave without working my notice, I don't know if I can back 5 weeks. I have a week off for half term so really it's 4 weeks but I just don't want to go back at all. I work for NHS, any advice please ?
