Don't know how much more I can take 😣

23 years old, have a 1 1/2 year old, 32w pregnant, trying to go through divorce (he was cheating), on the verge of being put on bed rest, and now they are saying that my grandpa probably won't make it more then a few days. My grandparents raised me since my parents died when i was two. I just dont know how much more grief I can take right now. The stress just from the divorce was putting me into preterm labor and on the verge of mental breakdown and now with him about to pass I honestly dont know what to do. I dont know why im posting this. I just honestly am so lost and hurting and have no one to go to. Why can't life just give me a break
