Hi there.
I am 3 months into a new job which I like. However I am also several months into counselling dealing with sexual abuse in my childhood, and it is at a very difficult point. I can't concentrate on my job, I feel like a rubbish employee, and my line manager is starting to notice. My head just feels so full all of the time, like I am constantly working to calm myself down and convince myself I will be ok and can get out the other side. With the result I am distracted and cannot focus. It's starting to make me dread my work.
I have no idea what to do. Should I try to tell someone at work? We don't have a HR dept. My line manager is a very kind woman though, and from a previous conversation I know she used to volunteer in some capacity at a rape crisis centre. I feel it is unprofessional to disclose something so personal, but it is the truth. The way it is affecting me means I'm not being properly professional anyway 
What would you do?
