My baby's funeral is tomorrow and I'm balling out of control

My son Hercules, his funeral is tommorow afternoon. He lived up to 18 weeks old and I delivered him at 20 weeks. I can't seem to stop crying and feeling like a wreck😭💔😔. Tommorow is the last time I will ever get to see him, hold him, and talk to him. I feel like all of this going on is a horrible dream, but it's not! It's my life and I don't know what to do. I'm just so lost. Sorry for the rant ladies but I just need to let somebody know how I feel😭😭💔💔👼🏼 how did you guys over one the fried? I feel like everyday I am just becoming more and more depressed. I can't deal with the pain and all this that I feel :(
