SUPER EMOTIONAL

I have 10 days before my period . I'm SUPER emotional . I mean I'm literally crying about everything . For some reason it's about losing family members or my boyfriend to death. I'm so scared. And I'm balling my eyes out . I don't want to lose anyone. I know it's part of life. I just don't know what happens after death...I just know that I will end up alone... Help. I don't want to think this way.
