Sheesh, I am now older than 35 and have tearful days during the "emotional" time during my cycle. I cry because I had a bad dream or they didn't have my kind of bread at the store. I cry at sad songs. Bite my hubby's head off for breathing and then cry and apologize. Then about a week later I am fine.
I would write down in a daily log and mark the days on the calendar. You will get a more clear picture with that. I would also take down water, meals, acitities, friends, exercise, big changes, family visits, etc. to see about a link. After a few more months, you may see a pattern, and can take action accordingly.
I think that just by noticing you are doing an awesome job. I would be careful to put her on meds until you can get a bigger picture. She is truly going through an awful lot at her age. Developing bodies, changing grades, peer pressure, hormones, boys etc. I think that asking questions and being open to exploring her feelings is great. Heck, I have a boy that is 13 and extremely moody. I have found that alone time with me, away from his brothers works wonders. It keeps us in touch and lets him deflate with out any bickering with his brothers. And sometimes he cries from all these "things" as he calls them. He just gets frustrated, and doesn't always know what to do. SO, we go to starbucks, spend a little quiet time and fix the world, answer questions, talk about issues, friends, problems, etc. And ressure him that I am here for thick and thin. And to come any time he needs help, or alone time, talking etc. Then he feels better and able to cope. for about a month, and then we have growing pains again and then we go for ice cream and talk, then next month do the whole process over again. we have had some very interesting conversations about peer pressure, bossiness, responsability, college, pre-marital sex etc. some very profound things come out of his brain and mouth.
i would watch her. journal everything down to bowel movements if you have to. as long as she is not suidical or into hurting herself and others.
then if it doesn't get better then I would go talk to the doctor.
They are also our for school and she will probably be going into another shcool in her next grade level and she is probably sad and anxious and excited all at the same time.
I think that you are doing great. Very observant mom.
