anxiety attack

Well not sure why but tonight just took a huge toll. I was already mildly upset because my boyfriend had canceled our plans for the night but luckily my friend still went. But all the sudden I get hit with a wave of me internally freaking out. I wish I had him with me so he could comfort me but unfortunately he was with some buddies. I have anxiety pills but they are too strong and knock me out and I don't want to sleep. Any natural ways to soothe anxiety?
