I'm in that situation where the tiniest things set me off, too (more of an instant rage sort of deal, though). The only advice I can give you is to keep fighting. Take it day by day, hour by hour, minute by minute. Even if it's hard as hell, look around you and find something you can smile at. Something that can brighten up that second. Believe me, it's there. Keep doing that to keep going throughout the day. Play with your dogs and go to bed. Do it day after day and maybe, just maybe, things will get easier and better for you. Wish you luck.
