I pray and ask in the name of Jesus to give you your confidence back. I used to feel the same way you did at work. I thought people were looking down on me. I found out they were because I knew I had the Lord in my life and this was the enemy hating me. When they start looking down on you do as I did, just pray the blood of Jesus. The enemy wants you to feel down, dont let him win. If you feel down then he has defeated you. Dont let him win. In the name of Jesus I pray that you will get your confidence back. Whatever you do keep your income and dont let the enemy get to you, dont do as I did and leave your job. Dont let the enemy get to you, you have the blood of Jesus not him.
