my world is crashing down around me

Literally the worst day of my life. My mom, my best friend passed away today for unknown reason at the age of 38. I'm due in two weeks and she was the most excited about my little girl her and I were her world and now she will never get to meet her... I haven't really even cried yet. I'm only 18 I'm not supposed to live without my mom... I know it makes me sound like a child but I want my mommy😔 I don't know how I'm ever going to make it without her I really don't, but if I can be half the mother she was I'd be doing good. This is going to be the hardest year of my life. It was just last night we were watching tv drinking hot chocolate. Sorry I just needed somewhere to let this out.
