Icry, I´m truely sorry for you. I think I can imagine how you feel!
I´ve always had some sort of social anxiety. But with mental illness, this can get so much worse.

Are you in therapy? If not, is there a way to get it?
Your therapist would help you with this situation and support you and that can be so valuble. I think that some people are introverts and some are shy naturally.

However, with therapy you can raise self-esteem and assertiveness and it will be less distressing to be and work with people.

You´re not feeling bad because of you, but because of your depression.

Until you get better, maybe there´s a way where you can work from home or someplace where you work by yourself most of the time, even if you see other people from time to time. Like an office job.

I don´t know if this is relevant for you, but delivery comes to my mind.
E.g. mail people don´t usually have to interact with people, I think...?

Don´t give up and if you have any chance at all, don´t do anything that makes you feel worse.
