If I were completely honest on my CV and sent it off, any hiring manager would take one look at it and come to the conclusion I have serious issues going on with my life. At root of my problems is ADHD, which was undiagnosed until age 35. Throw alcoholism into the mix and you get absolute destruction.
You can't lie anymore because of the thoroughness of the vetting process in this day and age. I've been caught in a lie on my CV before and had my job offer rescinded. I have 4 job offers rescinded. I am essentially unemployable besides menial jobs that don't bother with background checks. I am 43 now and really at a loss about what to do. Volunteering may help people with timeline gaps, however, in my case, wouldn't make difference. The only thing I can do is stay sober and buy lottery tickets. Winning the lottery is the only way I can think of as a solution. If I were a little older, I would be contemplating suicide.
