I've stated before that I'm dyslexic...
It negatively effects my work, such that all of my life I've been unable to advance beyond manual labor.
Unfortunately even manual labor seems to be beyond my ability. At least the job I'm currently working seems beyond my ability. I can't at all seem to meet either time, or quality (error free) work.
Thus I don't know how much longer I'll be working at my current job. I honestly feel utterly depressed about my lack of ability to do anything useful.
