When I was 11, I became depressed and anxious. My anxiety was caused by a fear of death. If I didn't accomplish "enough" that day, I would become anxious that I didn't live my last day to the best it could be. Then, I would be scared that someone would come and murder me in my sleep, so I had to (and still do) listen to loud music, have my fan on (even in the winter), and leave my lights on so that I could be "safe." If I didn't leave the house that day, I would also become anxious. After I became a vegetarian at 15 (I still am 15), my anxiety has generally gone away (I still have really bad anxiety during thunderstorms).
Since November (2 months after I became a vegetaian), I have been having a weird feeling. It's kind if hard to describe, but a lot of the symptoms are similar to those of mania or hypomania. The first time this happened l, my brain felt overly full, couldn't stop moving, weird things bothered me (I took sugar packets out f one of those holders because there were to many and they were sticking out. I also couldn't take my attention away from a curtian that didn't match the others. I was the only one to notice, and it kept my attention for a half hour), I don't really remember anything I said, I was sped up. This was 3 days before my period, and similar symptoms have been happening in a simlilar timeframe.
I also feel depressed for about a week sometime every month. I feel like crying constantly, all I think about is either dying or cutting myself (I only cut myself once and I've stratched my arm to leave marks that last longer than 12 hours twice), and I generally feel sad.
For a day every month, I also become extremely irritable. I'm nice to my friends, but if you're anyone else ;including my parents), be prepared for constant sarcasm and snappy responses. Weird thing bother me, like my mom hitting the brakes on the car a little too hard, when in reality, she's seining the same as usual.
If I didn't describe anything clearly (I'm terrible at describing anything using writing) feel free to ask questions to clarify. I don't know if I should seek psychological help or birth control pills, and I've ne'er heard of anyone having these types of symptoms when they're PMS-ing.
P.S. These symptoms are generally spread out throughout the month, so the only tine I feel happy and normal is when I'm actually on my period.
