> If I make a mistake at work and people are aware of it I am afraid that it reflects negatively on me more than the good things I do reflect positively.

This happens all the time. Though making mistakes are parts of getting experience.

> That fear of making mistakes makes it difficult to appreciate constructive criticism. I do appreciate it on an intellectual level but on an emotional level I feel more fear than appreciation. That the risk is that making any mistake could cost me my livelihood

Past experiences might drive you to feel this. Take a step back. See things objectively. Stop being paranoid.

I felt this way months ago. Then I looked around, things will be more fragile if I'm not there to support it, therefore I'm important.

I continued moving, making calculated mistakes, so are those who work with me. I progress, perfect myself, and so can you.
