I am a severe stutterer in IT. Interviews were always hell to me. Probably failed a few due to not being able to articulate my answers and thoughts properly. Landed a few jobs simply because I think the interviewing managers were understanding and cared more about my resume and liked me. Had 2 long term jobs in IT, and pivoted to data analysis 10 yrs ago at a major US hospital. Do not get discouraged. I feel your pain, as I do also struggle with mental health for many years. It is difficult. Not a day goes by that I think about how stuttering had many doors closed for me that required public speaking and communicating with others. Dont give up. Life is a struggle for many. Keep working on it. Recently read a book “Man’s Search for Meaning” by Viktor Frankl. Definitely put some things into perspective. Good luck!
