I got a little out of control tonight. I nearly got in a fight (a physical fight)

My neighbor had people over who were parked in my parking space. I was so pissed when i saw this.

They said they were going to be only a minute, so i decided to temporaily park in another neighbor's spot and just move when they were done.

I got stuck in the snow. I was SOOO Pissed!
I started yelling and swearing. It was frustrating.

so some total stranger helps me get my car out. (he was soo nice)

So then I get my car back on the street and the woman tries to explain what's going on, and says that they will only be a few minutes. I explain where visitors are supposed to park, and tell her that i wasn't really mad at her, mainly getting stuck in the snow.

Over 30 minutes pass.

She comes out, and i tell her they need to move their cars *now* I was very very rude and angry with her, but i was losing my patience because all i wanted to do was get the f-k home! There was no where else to park, and I couldn't leave my car on the street or risk getting a ticket or getting it hit by traffic.

They finally came out and move their cars, and when we were both headed back towards the building she started *****ing at me again, i just kept saying i just wanted to go home. I wanted to f-ing smack her. Really wanted to just beat the **** out of her.

I of course didn't. I ended up putting away my groceries and i went for a walk to blow off steam. They were gone when i got home.

I've been so short with people lately, just snapping when i dont mean to. The foulest language is coming from me all the time. I almost hit my cat yesterday.

What's happening to me?
