boss sleeping on the couch


Hello,
I have the thought that: “I don’t like others not liking me.” I don’t like to think I am left alone, that makes it scary.
Last week my boss asked me to be more into the management of the agency, but when I did the plan for the week he was the one not following it.
C When I pointed it out to him, he told me: you are too straight in your job and too fast for me
T I was not doing the job in the right way
F Insecure
A Worry about being fired, doubting myself, thinking he may ask someone else to do the plan, thinking I am too bossy and I don’t want to be bossy
R I was convincing myself that I am not doing the job in the right way

How can I change my thoughts and be more sure about myself?
Thank you.
