Any advice surrounding grief?

Yareli

I have an almost 9 month old,8 year old and I am 3 months pregnant. Last week I lost my mother to pancreatic cancer. Within 5 months of being diagnosed she passed away. She was a single mom but I adored it that way because that meant she gave us double the love that any child deserves. Is there any advice to be able to be strong for my babies? I still feel like she went on a trip and that I will see her in no time. Next week she will be cremated but I just feel so overwhelmed. She was my whole world 😭
