I am stuck and I need your experience, ideas, and help.
Background story. I have a supervisor who is giving me critics and always lowers my confidence. For example, when last year I wrote a paper for a workshop by myself, he told me I suggest you not to submit because you will burn your name and this is horrible works, etc. He then said if you insist on sending it don't put my name!!! He also didn't allow me to apply for a doctoral symposium (the most prestigious one, he said you won't benefit). After a year, I was really disappointed in my own work, he was on holiday, and I thought my work is valueless. He also criticizes me for not publishing anything.
My issue: He was on sick leave, there was a conference, and I had some work that if not for this conference, it would be useless for anywhere else. The conference is a C level(computer science) but the only conference in this area of work and all important people in the community are there. I wrote a paper, and because I was really disappointed I submitted it to get some feedbacks. I mentioned my intention of sending the paper to him in an email, probably he didn't see anyway. As a result, he wasn't there and I submitted the paper, now it got a conditional acceptance. This is my first time writing a paper and I was new to the submission. The conference was double blind, and that was why I submitted it anyway. I didn't know where I should put his name or how to submit, I did it anyway.
Problem: Now I am scared to tell him about the conditional acceptance. Should I tell him or just refuse from doing the revisions and acceptance? How can I include his name(I thought initially it would be in the camera ready version, but the email says it is just me as the author)? What should I do? Instead of being happy for my first paper, I am worried and close to nervous breakdown. What should I do? Please help me.
