I'm in your same 'hypomanic' boat.....I did the same thing back in 96...Had a good? relationship, bought a house.....was ridin high on the crest...never got a pet, but if I had thought of it I would have. Got two cars within a year because I felt so good about the future I was building. Then the bottom droped out. I can't really picture the day, week, or month.......but I lost it all, little by little.....
That is my sad realization...but...At least we can look back and try to understand what the heck happened......try to move on and not let it happen again.
Good luck with your dog....you seem a truly caring owner....and a pet seems to help many heal.....

.......Y..
