I'm a nurse and I have returned to work following Mat Leave. I only took 3 weeks of ML because my DH enjoys looking after DD and she's so easy to look after- slept though since 4 weeks, rarely cries etc. For a few weeks I have been really forgetful and absent minded. I've thought that I was doing a good job and then at the start of the next shift I'll have remembered I didn't hand something important over or that I wrote something down in the notes that didn't make sense. I had also been waking up with numb hands and feeling drowsy. The workplace is horribly understaffed and I didn't want to go on the sick or give my new managers the impression that I can't cope with work and a baby. I've since been to the GP after I nearly passed out at work and they've said that I have had a viral infection brewing for the past few weeks.
Essentially I've given my new managers a dreadful first impression of myself and I'm convinced that they think I'm a blithering idiot that should never have been registered. I've done a reflective account of the past few weeks to demonstrate that I have regretted not investigating my illness, telling my managers or acting upon it appropriately. I also feel like I need to give myself and my managers more confidence in my abilities. I was so good at this job and I know that I have in no way been myself in the past few weeks. Is there anything else that I should do to demonstrate to my managers that I'm not stupid or incapable?
