PMDD Problems. Help!!

 I'm fifteen and for me, PMDD is absolutely destroying my relationships. I have random angry outbursts for no reason, I feel so so hopeless, and I can't function until I finally get my period! It's so draining on me and my family; especially my boyfriend, the poor dear. Are there any other women here who have this and can help me find natural remedies to calm down during this time? I'm set for a period in 8 days, and I can't do this for much longer! Any help or advice is really appreciated!!!
