Have waswas and depression on meds so my short term memory/ concentration is poor. forget which rakat I am on (1-2 daily) and add extra too often when I can’t remember and this is tiring, prayer begins to feel too long. I therefore go off my feeling what I think and don’t do extra rakat. Is it ok?

Ustadh AbdulAziz al-Haqqan
This is waswas, so do not follow it. When doubt about the number of rakat comes to you often, ignore it and go by what you think is most likely, and nothing is upon you. Do not add rakat for it. May Allah cure you and ease your affairs ameen.
