I started a new part time job a month ago after being unemployed for about a month. It started off OK, it's retail/health. I had 3 days experience with a colleague (who I job share with) before I was expected to open, run and close the shop on my own. And of those 3 days I was hardly with my colleague, I was sorting things out in the back room. I was also given extra duties to carry out on top of my retail role which my colleague doesn't do. So I'm trying to do two jobs at once and making a mess of both of them because I don't have the time. If I'm working and I'm off the next day, my boss will ask me what I'm doing the next day along the lines of can you come in to work. Again my colleague doesn't get asked this. I'm also expected to cover for other stores, again only me.
Because I can't do my job properly as I have far too much to do, my colleague is getting annoyed at me and leaving snippy notes, and my boss is getting annoyed with me too. It makes me feel so anxious and upset, I come home and all I do when I'm not at work is worry about what I've not done at work and what I'm going to get told off for on my return. I get blamed for things that are outside of my control as well. It upsets me a lot that they are taking the piss out of me. I can't do it any more, I have no contract so I'm going to call my boss tomorrow evening and tell him that I'm sorry but I won't be back. I'm terrified to do it though.
The problem is though, I'm so co-dependent and I have things really twisted in my head. I feel absolutely shit for working there but I feel just as bad for not working there and wanting to quit. I feel like a quitter and all the old feelings came back, like I'm just a waste of space, a loser, I'll never amount to anything, I'm a joke etc. My DP has been really amazing and told me that my happiness is far more important than this shitty job. It's bringing up a lot of my negative feelings about myself and I don't want this to turn in to a full blown depressive episode. I don't know how to cope with these feelings that I'll never be good enough and that I'm scum, and a waste of oxygen. I almost feel like I'm sub-human, does that make sense? I have had counselling but they won't go away.
Even after typing this out and reading it back I know I'm not being unreasonable for wanting to quit, but I still feel awful and really upset. I don't really know what I'm posting for, just.. I don't know. I don't want to feel like this any more.
