thanks for sharing those responses with me @Jlol i can see that work takes up pretty much half your day, makes sense why you'd be tired! but at the same time, balance is super important. and the fact that you feel so extremely drained constantly is a big sign that some changes to your work-life balance may be needed.
do you enjoy working in IT? do you find the work hard? i know that in some of my previous roles, it wasn't the work itself that drained me but my manager, is that the same for you? and you mentioned your doing extra hours to make up for your time off, how much longer do you have to do these extra hours for? seems quite intense!
do you work on weekends too? sometimes having something to 'look forward to' at the end of the week help, and it doesn't have to be anything big. maybe its just a movie night at home or treat yourself to a fancy dinner or catch the sunset at a beach/look out spot. are there any interests/hobbies you've had in the past?
