Hi I have had several episodes of stress last year causing me to go off work sick last month. The final one being a work conflict issue that has now been resolved but I feel mentally exhausted by it all. If I try and do anything I start to get fast breathing, fast heart rate and muscle tension. If I go out I feel weird and almost detached. I’m also unable to sleep as well without medication. Has anyone else experienced this and how long was recovery for you thanks.
