Not follow planner

I’m unable to follow planner as at home I’ve a toddler and at work I’m on call so I keep getting work with no fixed breaks. I joined scs more than 3 months now and I manage to do most of the planned things ( not as per schedule but they’re done)but certain things like reading and research keeps getting postponed.

C prepare for exam
T there’s no point as I might fail again
F fear of failure
A not study
R fail the exam

C prepare for exam
T I ve passed many exams in the past plus I had not studied properly last time hence failed
F ?
A study
R pass the exam

What’s the feeling I need to pick so that I do my planned research just like my other tasks
