Losing my mind?

I don't know what is with me. I am so irritable and snappy... I can feel myself being a complete and total bitch and I can't stop it! I screamed, I mean literally screamed, at Stefan yesterday. I feel like the nerves under my skin are just crawling and I keep wanting to just lash out over the stupidest things. And realizing all of this I just want to burst into tears. I nearly did once or twice. It isn't that time of month or anything related to that situation I promise. So I am just not sure what is with me!

I guess it is a little better today, but I still feel just not like myself!
