I've co-existed with my depression and anxiety for a very long time (decades). I was considered highly functional, so I was able to hid my problems from everyone, including wife, parents and children. My coping mechanism was to throw all of my attention into a job I enjoyed and avoid social situations. But an incident outside of my control wiped those mechanisms out completely, leaving feeling useless and anti-social on top of everything else. A second incident occurred last summer has made it impossible to focus on tasks, easily forgot stuff, no motivation and just generally feel like I'm constantly in a fog. To make matters worse, I've reached the age where long recovery methods aren't going to allow me to enjoy life. In short, a life wasted.
Until recently, I never resented my depression as I had it well under control. However, these past few years have been hell as my world has slowly crashed down around me. Part of me would like to pursue recovery, but I don't yet see that as living - merely existing. Part things I'm just wasting our limited oxygen supply and I should leave this planet for others who want to be here.
Regardless of my feelings, may you find a technique that works for you - as I do believe it's possible to co-exist with some mental health issues. I wish you the very best and hope you find what you are looking for.
