Loestrin 24 Fe and worthlessness

I'm 21 years old, this is my 3rd brand of birth control pills. I've never had a problem with the pills I've had in the past, but I've moved frequently and my insurance changed. So my different doctors prescribed different pills. I started taking Loestrin 24 Fe two Sundays ago and since have had constant nausea and occasional vomiting. I've not only had mood swings but also extreme depression. I am usually a very upbeat and "happy-go-lucky" person but lately and very randomly do I find myself with thoughts of worthlessness and unprovoked guilt. I attend college and have even missed a couple of classes because I didn't feel worthy of going. I usually have clear skin with occasional small breakouts before I menstruate but currently found my face to be broken out all along my chin area and am not due for another period for another couple of weeks. My reasons for taking birth control have changed and I believe I am going to discontinue my use and notify my doctor.
