Grief during Pregnancy

I’m becoming a first time mother, I took my first pregnancy test on Monday, Tuesday I took another and both were positive. Wednesday I went to the dr to confirm and it was true. I was estimated at 7 weeks. Yesterday became a nightmare as my best friend was in a car accident and passed away. I would’ve never dreamed to wake up to know that she had passed to the other side. I’m having a hard time believing it’s true, bc I don’t want it to be. She was the first person I told about my pregnancy, I was ready to have her by my side the whole time but god decided she had a greater purpose. If anybody has tips or advice for me on keeping myself comfortable and calm at the funeral? There is no date as of now. All I know is it’s going to be very hard for me as she is the one I confided in always. Any kind words or advice is appreciated 😞 I am heartbroken.
