Heya Nina, sorry for what is happening at your workplace, its obviously upsetting you and I can see why but have you tried talking to your manager? Maybe she's doing it to try and help you both work out the situation because obviously there is tension between you and this other staff member. It may be worth speaking in detail with your manager to explain exactly how you feel. It's not worth leaving until you've at least tried. Plus what damage can talking to your boss do if you already dread getting up in the morning etc. Hope this helps. Love C.T. xx
