Panic attack/ mental breakdown

So I had a full on mental breakdown tonight. I have been really irritated with my hair lately and have been wanting a friend to help me cut it. Well she kept bailing on me. So tonight for some reason, I grabbed scissors and cut my hair.... It looks horrible and I'm gonna get it fixed tomorrow, I was just in the moment and it needed to be done... Has anyone had a breakdown/ panic attack like this? Where something so small pushes you past your breaking point and you just snap?
