Ever since I returned from a substantial timeoff due to serious sickness, my manager has been very critical of me. I still complete my tasks and get my job done but because I'm still sick and not yet back on my feet I'm not yet back to my previous form. My manager criticizes and castigates me and nitpicks everything I do, and I don't feel like I have his support. His behavior towards me is draining and causes me a lot of stress.
What do I do about my manager not being considerate of my sickness and not giving me the support I need while I get back on my feet? I want to tell him, "Hey I have a serious sickness and was off sick because of it and I'm still sick, you've been very harsh on me, I need your support while I get back on my feet" but I don't know if this is the best way to confront him, this manager might call my sickness an excuse. It's almost as if my manager is angry that I was off sick and is punishing me for mistakes and not being at the level I was pre-sickness. He hasn't accomodated me in any way.
Additional question, would it help if I told my manager details of my sickness?
To be honest the whole team has been indifferent towards me since my return.
