too early for a midlife crisis?

After I spent three glorious days at the beach with my kids, I came home with the kids only to find a seriously foul mood decending on me as I drove home. This is unusual for me. Usually the beach is fun but home is nice. After getting home my mood went further and further south. Crabby and snapping at the kids and just being an all around pill to be around. I sat and tried to analyze my motives, and it finally occurred to me, I didn't want to come home, to come back to the life that waited for me here. My job, living with mom the stress, all of it is becoming too much. Everyday that goes by the walls seem to close in just a little more. I have spent the day weighing several fixes, everything from a new tattoo to walking into work tomorrow and quitting my job. I really don't know how to fix this. I don't make enough to move out and in this economy I don't feel secure in quitting without something lined up. I've been feeling progressively more and more isolated recently and I think the ever increasing stress is mostly to blame gfor this. For once, I'm at a loss. I feel who I am shifting but for once I have no plan or direction. I need to get out of this rut I'm in but I can't find a shovel. So another day goes by and I wiggle an inch or two deeper into my rut. I need a change. Stay tuned, I'll let you know as soon as I figure it out.
