Nervous Nellie?

Lately I don't know what it is but everything that I do makes me just about jump out of my skin.  As hard as I try I can't calm down it's awful and it's causing me to freak out about the little things.  I will be texting Aaron one minute and then it takes him a little longer to reply and I freak about how he never has time for me.  I feel like I don't even know what to do with myself anymore to make me calm down because its not exactly healthy to get upset with people all the time.  I just wish I could be really truely happy again. any ideas how I could make myself calm down? thanks xoxo
