Insecure at work

I believe I am respected at work but a new person was hired and I find myself feeling jealous and insecure.
Intellectually I know my thoughts are the problem but I cannot get past them.

C: another person at work
T: She is good at her job. She is better than me. I will look bad to others. I didn’t do my job well before.
F: insecure and less worthy and jealous
A: Just feel bad
R: Still feel bad

Thanks for your insight
