It's just a part of his personality, not from a disease or aging. I should have known better than to cohabitate with my dad, but I felt a sense of responsibility after my mother passed several years ago. No, they weren't together, but had separated in 1981, but it didn't matter.
As far back as I can remember, he's had a short fuse. Even the dumbest, smallest things could set him off. I had hoped aging would "mellow" him a bit, but no such luck.
Here I am over 5 years into it and miserable. I write on forums/discussions and my own blog because it seems to be therapeutic for me. It also helps me forget, as I concentrate on crafting my words, paying more attention to syntax and grammar and less to meaning.
It's no easy task since I now have no source of income and my psych nurse practitioner thinks I may have chronic fatigue since none of the remedies/meds I have been given seem to help (they treat chronic fatigue as a disease by elimination). I get no social security since none of those doctors thought I was sick enough and I was in my late 30s (now 40) when I last got examined. I tell you this not because I want sympathy, but because people always suggest the obvious when trying to help. It doesn't work here.
The other thing I want to mention is that I'd really like for people to read my blog and feel free to send criticism and/or tell their own stories. My online friends think the blog is pretty funny, but I'd like people who know nothing about me to read, maybe even share :) Not only is writing therapeutic, but laughter is as well.
Thanks for reading :)
