A few times this past two weeks I've had some mood swings, but the one that happened tonight scared me a little. I'm a little stressed over a paper due tomorrow, and then me and my boyfriend wanted to get some food so I was looking for my keys, and with in seconds I was angry that I couldn't find my keys and how much a mess my room was. So we finally leave and i'm doing okay but when we got to the place to get food I couldn't get out of the car. My boyfriend went in, and I just started to cry. ( I didn't even get any food. And I really wanted some) So we get home and I just start crying even more kind of uncontrollably. And this all happened in about a 15 min time. How quickly I went from fine to mad to sad scares me a little, and I know my boyfriend doesn't know how to handle it, and he's getting frustrated, and I'm getting frustrated about it.
I'm already diagnosed with Depression, and on medication for that. But this is nothing like depression.

And thoughts would be really helpful , thanks
